  1. Hello, I have a city map with lots of building plans, most of them are 3D polylines and all of them has different Z values, according to their heights. I want to make a 3D model out of it by simply extruding them. But those 3D polylines have vertexes on different elevations. Is there a way to find a geometric center for each of those 3D polylines and flatten them into 2D polylines that has the Z value of that geometric center. So that I would have 2D polylines with different Z values. (I don't want to flatten everything to Z=0) Thanks in advance!
  2. Hi guys, I have 3d polyline net system as you can see down below, trying to measure every cell automatically (see attachment), problem is that net is 3 dimensional and hard to define measuring angular, every 3d polyline is individual (see attachment) just want to select the 3d polyline and giving measures between nodes, do anyone know how to solve this puzzle an easiest way? Best Regards
  3. Dear friends, how long I was here!... I need some help, if someone knows any lisp to convert Lines in 3D to 3D Polylines. The goal about it is to do a Pipeline tubes in 3D way. Thanks a lot for any help. CafeJr...
  4. Hi there I am looking for some kind of lisp to import points or 3d polyline along with a reference line. I am attaching reference files for study. thanks Bridge Plan.dwg Profile Data.csv
  5. hi, I wish to know how to extrude polylnes to 3D solids in autocad? I am new in cad, and i have around 100 shapes with height but in polylines, so i have to extrude.. i need someone to please tell me how to do this.. i searched online and on utube, but i found only how to draw directly. For my case i already have my 3D polylines. i need to extrude.. I am grateful for any help.. kay
  6. Hi, I would like to know: are there any lisp that can calculate the DIP and the length of a 3d Polyline, in Front View or any other view?
  7. Hi all, I have surveyed some pipes below the ground and I need to represent these as 3d polylines in Autocad below a ground surface model. Is there a routine that will let me add a z value to each vertex along a 3d polyline line which references a 3d face/ground model above to give me a true z value directly below the ground level. Any Ideas???
