Importing 3d points Autocad file

MLUY · 30 Mar 2021, 14:36

Hello, I have an issue with importing an autocad file with (xyz) points in separate layers. Each point is imported as a separate group consisting of a "X-cross", so when I explode the points I am left with 4 lines per point. What I need is a singular guide point for each crossing so I can triangulate the layers.

I have found some plugins that can forexample convert each end point to a guid but thats not a very nice solution. Does anybody know a plugin that can actually provide a guide point for each point where lines are crossing? Or any other solution would be great.

Doing it manually is not an option as there are way too many, I have attached my file

Thanks for your help

I was a bit fast posting this, but maybe for others having the same problem
I just found the plugin I need: its ThomThom Guide Tools

It has an option CPoint at Edge-Edge Intersection (v1.2.0) Adds a construction point where the selected edges connects. Note: only "loose" edges - edges that is not part of a face.

Great !, what should we do without ThomThom!

The file you upload has all the X-cross components exploded. If you leave the components unexploded you should be able to edit the component, put a guide point at the intersection and erase the lines. Then explode all instances of the component to leave yourself with a cloud of guidepoints.

I was going to make an example using your model but at this point it would be very time consuming to put the components back.

Thanks Dave, I exploded them because I thought it would be easier to work with most plugins. But are you suggesting I do this manually ?, there are thousands of points

No. I'm suggesting you don't explode the components until you've replaced the geometry inside with a guide point. Since all the X-cross objects are instances of the same component, you only need to edit one of them if you don't explode them all first. After you make the edit, explode the instances to leave the guide point cloud you are after.
