Importing CAD wire mesh to Inventor 3D sketch

[josee_laplante95TJJ]

Hi,

A colleague has done a wire mesh in Autocad2022 that I need to import in Inventor2022. I tried open and import, exporting various format dwg, dxf, igs but I can never get the required result. Are there things Inventor does not recognize such as dynamic blocks, blocks within blocks or attributes that would prevent the import/open to work perfectly because his file probably contains some/all of those?

The best visual result I got was using the dwg as an underlay but after I can't create 3D sketch to include geometry since I'm unable to select any lines/polylines while in 3D Sketch mode and I don't know why. In all my other trials I don't obtain the wiremesh only surfaces or empty parts.

See attached the dwg. The result in Inventor should be a 3D Sketch exactly like the cad.

Hi

Try this:

1. New part
2. Model 3D -> Create - Import
3. Insert the dwg file on the selected plane and at the indicated point
4. New sketch -> Select the workplane that matches the inserted skeleton (Create a suitable plane for other directions of the skeleton)
5. Sketch -> Create -> Project -> Project DWG

It works

This is what I understand from your instruction > I need to create multiple planes that match the various surfaces of the skeleton. Then project each face on a 2D sketch. But how can I create the other planes if I can't select dwg geometry to place it onto? As you can see the wiremesh as angles and slopes.

Am I wrong in saying I would have to have a least one face aligned to an origin plane and then work around the skeleton to create all other planes and 2Dsketches by selecting lines manually otherwise I will project information from all sides at once. I don't feel this is an efficient method in addition to being time consuming. For the purpose of this post I isolated a small portion of the entire building wiremesh I need to work with.

You can easily measure the distance between the armature points and the starting work surfaces.
On this basis, you can easily create construction points in space corresponding to the three measured vertices, and based on them, create a base work surface.
The rest is just a click away, as you'll create subsequent work surfaces based on both the existing sketch and surface.

You don't need to click individual lines to save DWG to sketch; you can drag the cursor and select the window.

I can tell you that it does not always work for some reason, maybe it has to do with the type of line in the cad file. With the selection window on an entire facade some lines where not projected, so I had to select the missing ones manually.

Also, I would Explode down to lines. (This would require special attention to some of the Blocks Reference.)
