Hello,
I'm trying to subdivide parcels where the client has given the areas he would like and rough locations of the boundary lines. The exterior boundaries are irregularly shaped 4,5,6 sided figures. Can anyone recommend a LSP routine or an efficient method? The attached is what the client provided. Your help would be appreciated, Thank You!

You could try using parcels but with the irregularity of the lot shapes it may be best to go old school and draft by hand.?ÿ
First you survey the outbounds of the parcel and fix all exterior lines, then you create the interior lines and verify the areas, then decide if it is close enough to meet the client's wants. Or did you want some magic formula that resolved you of all thinking and any work? It is called an iterative process.

He's asking about the Parcel Layout Tools in Civil 3D, not trying to ABsolve himself of thinking. Not sure how you jumped to that conclusion. Especially considering that subdivision layout isn't exactly rocket science; I sure as heck don't need to spend hours drafting by hand when I can simply tell the tool a few constraints to use and let it build the lots.
Concerning the actual question, I think that you could use Slide/Swing Line Create for some of those parcels, but as @squirl noted, it might be easier to do it by hand. I would start at the south end and start placing lines and see how it goes.

Personally, I know I'd spend more time trying to get the Slide/Swing line to work the way I wanted than if I just pencil whipped it. Granted, getting the parcels to work would be beneficial when it came to annotation, area tables, etc.
I think that it would be smart to bring a planner into the process. I mean, what about road access? Services? Building pads? There is a lot more to a successful subdivision than making areas work. Don't be a land butcher.
But as to the mechanics, what Paul says is the thing. Grind it out. Yes, C3d will automatically create some parcels for you which may be a starting point.?ÿ?ÿ
One AutoCad command you may find useful in the process is BOUNDARY. Resolve and draw the outbounds. Make it a closed polyline. No gaps or overlaps in the linework. Never mind the interior lot lines -those are irrelevant. Draw some dividing lines which cross those outer boundary lines (ie/don't worry about snapping to the exterior boundary lines). Invoke the BOUNDARY command and click within the enclosed area of the proposed lot. A closed polyline will be drawn within the enclosed area. Using that you can create closed polylines of your proposed lot configuration quickly, and speed up your iterations.?ÿ ?ÿ
Whether he is going to use "Slide, Swing and Create" or "By Guess and By Gosh" he needs to define the outer subdivision perimeter first. That would be the hardest part. As to creating the lots per the client's sketched wishes, as a professional he has a greater responsibility. The lots have to be build able, perced, have suitable grades, access and meet many other Code requirements. Actual lot lines and areas is the easiest part of the whole deal, after all the client thinks he has already done that job for him.

Hello,
Thanks to all for returning my post, let me provide some background. I try to ask shorter straight forward questions when I post to avoid miscommunication, in this case I was just looking for some ideas. Norman suggested the Boundary and Squirrel mentioned the time involved with the slide swing method which Rover confirmed. That's it, I hadn't used the slide swing and was wondering if it would be worth the time verses the trial and error method. I was just looking for something that would get me close area wise and save some time as Rover points out. Thanks for answering my question! I'll try to apply what you guys are suggesting mixed with what I've done in the past.
Further all of those lots have been platted and are on record, same ownership. I'm trying to put together a preliminary drawing to submit to the county which would address your concerns Norman. I've been working in one of those lots and have collected property corners and PLSS monuments that should help to address Paul's concerns. My intention is to do a thorough search of all section corners and all affected property corners as usual, for me this is the best part of what we do.?ÿ
There is not one part of being a surveyor that I don't care for, I can't think of doing anything else. To participate in this forum means something to me so thanks for your help!
Below is the said survey from Prescott, AZ the other is from Bridgeport, CA?ÿ ?ÿGreat weather, Beautiful country
Thanks Again, Paul
