Property limits lines for 3D Model Coordination

[cyberflow]

Hi everyone,

I'm trying to use my property lines to generate regions and offset them by a specific width, so I can "Union" them with a 3D solid extracted from a Civil 3D surface.

The goal is to bring this into a 3D model coordination viewer, allowing others to visualize and understand the property boundaries in context.

Ultimately, I want to represent the property lines in 3D within the Model Coordination environment.

Is there any tool or LISP routine that can automatically generate a closed shape from a widened polyline?

Have you considered asking this in the C3D forum?

[cyberflow]

It's pretty much a autocad question 

We're talking about property lines and how to create a closed boundary of a polyline with a width

[RSomppi]

C3D has some different tools and workflows. I can't say they are helpful for this but the users over there are more likely to have done this exact thing. Just saying...

@RSomppi Will be asking there too then, thanx for that

Will keep this one here too

@cyberflow ,

Can you help me by describing your workflow in simple terms?

Something like:

- User selects closed 3D polyline

- Polyline is offset by XX amount

- Region created from offset polyline

- .......

Best,

~DD

So are you looking for something like this, like a wall around the boundary?

Hi @CodeDing & @autoid374ceb4990 

Here's where i'm headed to :

I want to create a extruded property lines with a little thickness to create afterward a reference with 3D solids of that 3D solid interference so people can visualize in 3D the property lines

I hope my description is clear and please feel free to ask any questions

I think i've found something :

With the Polysolid i was able to extrude the 2d line : 

But i'd really like to add a width to that so it outstand more

If you have say 2D plines then you can double offset and cap ends then extrude. Here is an example.

(defun c:plcap ( / wid obj obj2 obj3 st1 st2 end1 end2 ent2 ent3 ent4 ent5)
  (setq oldsnap (getvar 'osmode))
  (setvar 'osmode 0)
  
  (setq wid (getreal "\nEnter width "))
  (setq ht (getreal "\nEnter extrude height "))
  
  (prompt "Select lines and plines ")
  (setq ss (SSget '((0 . "*line"))))
  
  (repeat (setq x (sslength ss))
   (setq obj (vlax-ename->vla-object (ssname ss (setq x (1- x)))))
   (vla-offset obj wid)
   (setq obj2 (vlax-ename->vla-object (entlast)))
   (setq st1 (vlax-curve-getstartPoint obj2))
   (setq end1 (vlax-curve-getendPoint obj2))
   (setq ent2 (entlast))
   (vla-offset obj (- wid))
   (setq obj3 (vlax-ename->vla-object (entlast)))
   (setq st2 (vlax-curve-getstartPoint obj3))
   (setq end2 (vlax-curve-getendPoint obj3))
   (setq ent3 (entlast))
   (command "line" st1 st2 "")
   (setq ent4 (entlast))
   (command "line" end1 end2 "")
   (setq ent5 (entlast))
   (command "join" ent2 ent3 ent4 ent5 "")
   (command "extrude" (entlast) "" ht)
  )
  (command "vpoint" "-1,-1,1")
  (setvar 'osmode oldsnap)
  
  (princ)
)
(c:plcap)
