Subdivision layout tips and tricks

[mboyce]

I am looking to discover tools that I can use to subdivide large areas of varying frontage.

Most of my professional experience is site work and municipal construction.

I have a template I built for private development that is specifically for doing alignment manipulation to do alignment changes to another drawing that drives the corridors, but I want to build in more advanced features now that I am starting this type of work.

I know parcels exist but I would like to be more of a power user with them. Parcels and pressure pipes (that I prefer using a workaround using profile by layout for pipelines) might be the main mysteries left for my in civil 3d until I install then next release and start messing with the auto grading tools though i am doubtful/hopeful for them to be useful.

Most subdivision layouts I receive look like they were drawn using vanilla CAD.  No magic involved, just rudimentary linework.

I personally use parcels.  I don't think they are too hard to use once you get familiar with them.  Just start with a few big closed areas and start dividing them up with the basic parcel line command.  You don't need to use the advanced tools like slide line / swing line.

When drawing the line, shift right click to access the snaps, I often use nearest or perpendicular.

I have attached a basic subdivision plan I did last week for reference.

I am having a hard time manipulating lot line once i have them and there seems to be some danger/glitches to adding PI to lines and the merge lots seems to leave behind things/not work as intended. It is probably just me not understanding it completely yet though here are some screens with what I have figured out.

I'm pretty stoked actually compared to how our private development does it currently as an array on a polyline. The amount of control and speed it redraws is a relief from the tedium i expected doing this. Is there a way to lock sites as they are completed (IE Block A has been recorded and sold etc.)

I will often draft out the initial approach with polylines and then create parcel from objects.  

A few other tips.  

1. Create a site JUST FOR your parcels.  If you use a generic site, it can cause problems when you have other objects (feature lines, alignments) on the same site.  An alignment will be very happy to sub-divide parcels when they are on the same site.

2. Parcels are the area labels.  Parcel Segments are the parcel lines.  Confusing the two can cause further confusion.

3. Make sure your parcel segments go all the way to the next parcel segment (don't have a 'T' with one crossing the other).  

This is an old post but most of these parcel rules are still applicable.  You will likely have a better understanding after reading it.  Thanks, and good luck.

No, it's not possible to lock sites directly. But you can change style for completed parcels to make them differ from the ones you keep working with. And remember you can always just lock the layer with parcels.
