In this exercise you’ll convert AutoCAD entities to Lan Parcels with automatic labels that show useful topological data such as land area parcel layout tools are available to create and edit Parcels with precision you’ll learn more about partial layout Tools in later Autodesk civil 3D tutorial exercises this drawing contains an existing ground surface as you can see here and several alignments that represent intersecting Road center lines and AutoCAD lines and arcs that represent property boundaries now in the following steps you’ll create Autodesk civil 3D parcel objects from the existing lines and arcs let’s start by clicking on the Home tab and then let’s focus on the create design panel click on the parcel drop down and select create parcel from objects go ahead and zoom into the east side of the site and I want to focus on the Parcels just north of the First Street alignment now AutoCAD within the command line is giving us the option to select lines arcs or polylines to convert into Parcels or we can even choose xrefs so we have several different options go ahead and select the outer boundary and select the inner lot lines go ahead and hit enter
now we have the create Parcels from objects dialog box we’re going to leave site at its default the parcel style we’re going to change to single family we’re going to change the label Style to parcel number and area go ahead and check the automatically add segment labels
and we’re going to erase the existing entities that we use to create these parcels then click ok the parcels are now created and labeled the labels annotate the overall parcel area as well as the bearings and distances for each line and curve segment these labels are automatically updated if any line or curve segment is edited or deleted the numbers with a circular border are automatically generated with parcel numbers you’ll change these numbers to use a more desirable numbering convention click the parcel number to select it now go up into your modify panel select renumber and rename
then we get the read number and rename Parcels dialog box specify the following parameters make sure that read number is selected select a starting number of 101.
we’re going to keep the increment value at one then click ok I’ll specify a starting point let’s go with the top most parcel
and then select the bottom most parcel
and then hit enter twice
you’ll see that the parcels are now numbered in ascending order with three digits so that’s how you create Parcels from AutoCAD objects in civil 3D in this exercise you’ll successfully subdivide a parcel with segments that can be placed along any lot line this exercise continues from creating Parcels from AutoCAD objects go ahead and open up your parcel Dash 1B drawing in your tutorials folder next go to your home tab and then to your create design panel select the parcel drop down and select parcel creation tools here we have our parcel layout tools toolbar go ahead and select this little drop down right here and select freeform create here in the create Parcels layout dialog box go ahead and accept the defaults and click ok
so let’s create some parcels I’m going to select the endpoint at this point in tangency by using my endpoint snap but notice that I have like a white construction line that goes across my cul-de-sac I want it to go in the opposite direction so I’ll move the cursor ever so slightly there we go I’ll click that location and then I’ll move my cursor straight up until it meets with the rear lot line so I have my first parcel I’m going to go ahead and repeat those steps by creating a few more parcels I’m going to select this location in the front and I’m going to move my cursor towards the back there’s our second parcel and notice that as I work my way around everything is automatically labeled so I’m going to finish up here by selecting the endpoint
of this point and tangency and I’m going to move my cursor all the way down and then I’m going to exit out of the layout tools so that’s how you go about subdividing a parcel with a free form segment in civil 3D in this exercise you’ll successfully subdivide a parcel with segments that are defined by their angle at the frontage this exercise continues from subdividing a parcel with a free form segment go ahead and open your parcel Dash 1C drawing in your tutorials folder and then go ahead and navigate to your home tab go to your create design panel and select the parcel drop down select the parcel creation tools next within your parcel layout tools toolbar go ahead and click this downward Chevron and we get this little dialog box here with some extra features I’ll specify the following parameters as you specify each parameter notice that the preview graphic is displayed at the bottom so let’s get started let’s go for a minimum area of seven thousand square feet
let’s change the minimum Frontage to 40.
next it’s asking us to use minimum Frontage at offset we’ll go ahead and leave it at yes but we’ll specify a frontage offset of 20.
for the minimum width we’ll go with 40 feet next for a minimum lot depth we’ll leave it at 50. for the use maximum depth we’ll leave it at yes for the maximum depth we’ll go with 200. for the multiple solution preference change this so that it uses the smallest area for the automatic mode we’ll leave it at off and then lastly for the remainder distribution we’ll place the remainder area in the last parcel now note that when the automatic mode is set to off the remainder distribution setting does not affect the parcel layout this setting will be used in later exercises all right now that that’s finished go ahead and click the upward Chevron and then select this drop down and then click Slide line create
now we’re in the create Parcels layout dialog box for the parcel style go ahead and leave it at single family and leave all the other settings at their default and then click ok
let’s move our toolbar out of the way here
go ahead and select the parcel label for lot 101 and then our command line is asking us to select the starting point of our Frontage let’s start our Frontage right here and then as I draw my cursor to the right you’ll see this yellow line go ahead and select the end point of this lot line our command line is asking us to specify an angle we’ll go with 90 degrees
you can see we have a little preview graphic of what our Parcels are going to look like now our command line is asking us if we accept the result we’ll hit enter for yes and the new parcel is created and labeled and a preview of the next parcel is displayed now for this second lot we’re going to change things up we’re going to change the minimum area in our dialog box to 8 000 square feet
do we accept the result select enter free yes as you can see our parcel was created with a minimum area of 8 000 square feet and the remainder area is shown within the last parcel when we’re finished go ahead and exit out of the command now go back to your toolbar select the drop down again and select the same command we’ll accept the defaults now in this instance change the automatic mode to on and keep the remainder distribution to place all of our area within the last parcel now click the parcel label 103. our starting point for our Frontage will be at this endpoint
and then move our cursor all the way over until we get to about the midpoint of this Arc specify an angle of 90 degrees and now a preview of our parcel layout is displayed go ahead and accept the result
and you can see that all of our Parcels are 8 000 square feet as we specified in our settings and the remainder parcel contains all of our additional square footage press escape to exit out of the command and that’s how you go about subdividing a parcel with the slide line in civil 3D in this exercise you’ll subdivide a parcel with a segment that swings from a reference point from the back lot line this exercise continues from subdividing a parcel with a slide line we’ll start by going into our parcel Dash 1D drawing which is located in our tutorials folder go ahead and go over to your home tab and then to your create design panel next select the parcel drop down and select parcel creation tools
now we get our parcel layout tools toolbar if you’re not seeing the parcel parameters make sure that this Chevron is fully expanded
for this lesson we’re going to keep our parcel sizing at its defaults and we’re just going to select this drop down and select Swingline create
now we get our create Parcels layout dialog box make sure that the parcel style is set to single family and select ok
now our command line is asking us to select a parcel to be subdivided and we’re going to pick that by selecting this lot label for 102. then we’re going to select our Frontage by roughly clicking this area right here and extending all the way around to roughly this area
now we specify our swing point go ahead and pan over and I want you to put your cursor right around the 2 in 102. and then from that point go straight up from there to the back lot line and click we’re going to accept the result and there you have it we now have a parcel that’s exactly 8 000 square feet which is specified in our parcel sizing under the minimum area and the remainder distribution which is specified to place the remainder in the last parcel is within our parcel 102. as you can see right here so that’s how you go about subdividing a parcel with the swing line in civil 3D in this exercise you’ll create an alignment outside of a site and move existing alignments out of sites these practices eliminate unwanted Parcels being created by alignments interacting with the site when an alignment is in a site it creates new Parcels if it forms closed areas by crossing over itself or other alignments or Parcels on the same site let’s start by opening up your parcel-1e drawing in your tutorials folder this drawing contains five roads off a main West East Road the two Northern side roads Each of which created a parcel in the roadway and cul-de-sac Center Island in the next few steps you will convert the center line of one of the southern side roads to an alignment and prevent it from forming parcels in the tool space go ahead and click on the prospector tab go to your sites and expand the sites now let’s check out the alignments
notice that the four existing Centerline alignments all reside in site one while the top level alignments collection is empty
go to the Home tab and then under the create design panel select the alignment drop down and then create alignment from objects and right now we’re being prompted to select our first line in our command line go ahead and select the red Center Line for the road in the lower middle of the drawing then press enter twice
the create alignments from objects dialog box is displayed and notice that by default the site is set to none go ahead and click ok
expand the top level alignment section and notice that the new alignment was placed under the alignments collection this happened because you accepted the default none site selection when you are prompted to select a site in step 3. in the next few steps you’ll move one of the two existing cul-de-sac Road alignments out of the existing site and into the top level alignments collection
in the tool space go ahead and select the prospector tab and right click on alignment 4. which is the cul-de-sac alignment to the northeast of the alignment you created click move to site
now we’re in the move to site dialog box make sure the destination site is set to none and then click ok
now notice in the tool space that alignment 4 has moved into the top level alignments collection in the drawing window the parcel label and hatching has been removed from the cul-de-sac Center Island as you can see right here for further clarification go ahead and repeat the same step for alignment 3. so that’s how you go about working with alignments and Parcels in civil 3D let’s start by specifying the parcel creation settings go ahead and open up your parcel-2a drawing which is located in your tutorial drawings folder then go to your home tab then to your create design panel click on the parcel drop down and then select parcel creation tools
in the parcel layout tools toolbar you’ll see this little arrow off to the right hand side we can collapse the toolbar or expand it
specify the following parameters as you specify each parameter you’ll notice that there’s a preview graphic that’s displayed at the bottom of the parcel layout tools window for this exercise the parcel sizing values have already been Incorporated so we’ll move on to Sliding a parcel line we’ll move this box off to the side and in the parcel layout tools toolbar
we’ll select Slide line edit
in the create Parcels layout dialog box go ahead and select ok you’re now prompted within the command line to select the attached lot line to adjust and the drawing select the lot line between Parcels 108 and 109.
select the parcel to adjust by moving the cursor over property 109 and as you can see the parcel borders are highlighted click inside the parcel now specify the starting point of the frontage I’m going to select this point right here and I’ll come along all the way over here and specify this point now enter a frontage angle of 90.
now you can see the preview Graphics of the partial creation parameters and proposed solution are displayed the displayed solution slides the lot line along the frontage at the angle specified the proposed solution encloses an area that meets the parcel creation parameters you specified at the beginning of the exercise go ahead and select enter so that’s how you go about sliding a partial lot line in civil 3D in this exercise you’ll resize a parcel by swinging an attached lot line from a specified reference point this exercise continues from sliding a partial lot line the first step is to specify parcel creation settings go ahead and open up your parcel-2b drawing which is located in your tutorials folder then go over to your home tab and then to your create design panel next click on the parcel drop down and then click on parcel creation tools
remember on the parcel layout tools toolbar we have this little arrow to collapse the menu and to expand it we’ll specify the following parameters as you specify each parameter if you remember we get a little graphic down here at the bottom currently for this exercise all the parameters have already been filled out so we can proceed to the next step now we’ll swing one end of the parcel lot line on the toolbar select this drop down then select Swingline edit we get the create Parcels layout dialog box go ahead and select ok we’ll move this toolbar off to the side
you’re now prompted to select the attached lot line to adjust in the drawing click the lot line between Lots 104 and 105. then we can select a parcel to adjust by moving the cursor over property 104 and clicking now we’re going to specify the parcel Frontage we’re going to start from this endpoint and we’re going to come around to this endpoint
now specify a swing point and move your cursor to this approximate location
now our command line is asking us if we accept the result go ahead and hit enter for yes lastly go ahead and hit Escape to exit out of the command so that’s how you go about swinging one end of a parcel lot line in civil 3D in this exercise you’ll use the feature line editing tools to modify partial lot line geometry you’ll use two different methods to change the geometry of the two large Parcels at the end of the cul-de-sac first you’ll learn about the grips that are available on lot lines you’ll use lot line grips with the feature line tools to change the geometry of a parcel second you’ll join two separate lot lines and then remove a point of intersection from the combined lot line this exercise continues from swinging one end of a parcelot line so let’s add a point of intersection to a parcelot line go ahead and open up your parcel-2c drawing which is located in your tutorials folder then select the back lot line between Lots 105 and 106. now you’re in the parcel segment tab go into your modify panel and select edit geometry now you can see that the edit geometry panel is displayed in the ribbon select insert pi now our command line says to specify a point go ahead and snap to the intersection
of the back lot line and the lot line that separates the parcels 105 and 106. click to insert a point of intersection press enter to accept the default elevation of zero press Escape twice to end the command
you can see now that the back lot line now has a point of intersection at the point at which the parcels meet with a pi in this location you can edit the lot line on one of the parcels without affecting the other let’s go about grip editing a partial lot line in the drawing select a lot line between Parcels 104 and 105.
if we zoom in
you’ll see a blue diamond which is our grip this grip is available on attached lot lines which are created with the slight angle slight Direction and swing line precise sizing tools available on the parcel layout tools toolbar you can use this grip to slide this highlighted lot line along the lot line which it’s attached press escape to deselect the lot line select the back lot line between Parcels 105 and 106.
now if we zoom in here you’ll notice a square grip at the end of the segment these grips are available on lot lines that were created either from the Autodesk civil 3D objects or the fixed lot line and curve tools available on the parcel layout tools toolbar you can use these grips to change the endpoint location of the lot line now after you’ve clicked the grip at the top of the lot line
you can drag it towards the lot line that separates Parcels 104 and 105.
type in the intersection snap to snap to this location
you’ll notice that the area for lot 105 has automatically changed however now we have an unnecessary blue lot line go ahead and press Escape
then select the blue lot line within the parcel segment tab under edit geometry select trim for The Cutting Edge select the rear lot line of parcel 105. then press enter now select the blue lot line to trim press enter to end the command
now let’s go about breaking a parcelot line select the back lot line shared by Parcels 106 and 107. and the parcel segment tab under edit geometry you’ll see we have a break button
now our command line is asking us to select an object to break select the rear lot line
and type in F for first point Now activate your intersection osnap
select this location
then press enter
you’ll see that two lot lines are now created separated by the point that you specified let’s go about joining two parcelot lines go ahead and click this parcel segment then go into edit geometry
and select join
now select this partial line
then press enter these two lot lines are now a single entity let’s go about deleting a point of intersection go ahead and select this lot line then under edit geometry
select delete pi
select this corner
and press enter twice to end the command
so that’s how you go about editing parcelotline geometry in civil 3D in this exercise you’ll control the display of overlapping parcel lines parcel style display order in civil 3D controls which lot lines are visible where different types overlap we’re going to go ahead and start this lesson by changing the parcel style display order go ahead and open up your parcel-3a drawing which is located in your tutorials folder go ahead and zoom into your site and you’ll see that some of our Parcels are magenta and some are blue go ahead and go into your tool space and then to your prospector tab expand the sites and expand site 1. then right click on parcels and select properties go ahead and move this dialog box off to the side here we’ll focus our attention on the parcel style display order you’ll see that single family is up at the top which is the magenta Style now this style since it’s up at the top supersedes all of the others and a parcel display order list go ahead and select standard which is the blue lot lines and we’re going to move that up to the top
then go ahead and click apply
now you’ll see after the model regenerates notice that the blue standard lines have overridden the magenta lines which are the single family lot lines we’re going to go ahead and repeat that step by selecting the property and then we’re going to move that up to the top and click apply this setting displays a light blue line around the extent of the site lastly go ahead and move the rode parcel Style up to the top and click apply you can see now that the road is now on top of all of the other styles let’s go ahead and move this style between standard and single family and click apply these settings change the display of the curved Road edges go ahead and click ok so that’s how you go about changing the parcel style display order in civil 3D in this exercise you’ll generate a map check report for the parcels in the residential Road at the top right of the drawing which is this region right in here in civil 3D you can export inverse or map check reports for either a single parcel or a series of parcels or all Parcels in a site this exercise continues from changing parcel style display order so let’s go about exporting the parcel data note this exercise uses the parcel Dash a drawing with the modifications you made in the previous exercise we’ll start by going to our tool space and into our prospector tab and then expand the sites expand the site one and expand parcels
go ahead and select parcels and you’ll get a list of all the parcels within this site
go ahead and select the number column to sort our parcel numbers
go ahead and scroll all the way down
and select parcel 120 hold down shift
and then click 136. so we’re going to select Parcels 120 through 136. however if we hover over 136 this is actually the road parcel so we want to deselect that by pressing Ctrl selecting it and that deselects this parcel from our data
after that in our Master list go ahead and right click on parcels and select export analysis
now we get our export parcel analysis dialog box go ahead and select a location for the destination file and I’m just going to put this on my desktop and I’m going to rename it export analysis and click save
for the analysis type I’m going to select map check analysis and then click ok
the export analysis text file automatically pops up in the text editor associated with civil 3D and it’s saved in the location you specified so that’s how you go about exporting parcel data in civil 3D
