  1. I have a converted dxf file (convert from an STL) which was used to create a 3d part and therefore must have been an enclosed volume (or the 3d printer would reject the file). But when I open the file, it has a series of 3d faces instead of a 3d solid. I have used convtosurface cleanly. But when I try to use the sculpt command it says it cannot find a watertight volume. arm-rugged_low-wall-v2.dwg I have attached the file without the surfaces as later files are too big. Is there any autolisp or script files that can check and highlight problem areas? There are a number of files I need to check. This is just one example.
  2. I have several files that have lost their geometric data that is usually there when they are primitives. This also removes the grips that allow me to resize the objects on the fly. Is there any possible way "apply" new data to these objects without recreating them? Is there a command, an express tool or a lisp routine that can accomplish this? TIA!
  3. Hey everyone, it's my first post on this forum:). First of all i would explain what i am trying to achieve. I have to write a program that match an 3d solid to a cloud point which represent this object. As far as i know there is no function in AutoCAD that return the shortest distance betwen an 3d solid and point, this would help me alot (i guess so). I think i could use bounding box, make one for the object and one for points (points change to smalest shapes and use union to create one object) - this will let me make bounding box. Next i have to compare the dimensions of this boxes and fit/match them. What do you think about this solution?, any opinions and other ideas will be appreciated. Ps: I know this idea is't pretty as my english. Ps2: I'm learning Visual Lisp for a half year so excuse me if i don't understand something.
