[REQ] Project visible edges on a plane

gude · 21 Oct 2010, 20:51

Hello
I'm coming from newbie forum.
I have been looking for a way to get a clean 2d geometry right out of SU but after googling a lot i cant find one.

Is it technically possible to create a script that projects visible edges (only the visible ones) on a plane? A plane like an imaginary 'picture plane' in Technical drawing that projects visible edges and prints them on itself.
When my plane is upright i can collect elevations from my model.
When i cut my model for a floor plan i would like to project the outlines of my furniture and uncut geometry on it.

***the edges projected on plane need to keep layer and group/component.

NB
2d dwg export results in a geometry with all components expoded even curves
3d export is nice but i wanted in 2d.
Flatten script is quite nice but it merges down the top with the bottom geometry and results in showing the invisible ones.

This would be quite possible.
For instance you could set the 'plane' using my 'WorkPlane' tool or similar.
Make your plane in the 'elevation' desired [or any other plane for that matter!].
Then select one WorkPlane AND the desired objects to 'project' onto it [geometry/groups/instances].
The selection is processed.
The plane is derived from the WorkPlane.
A new group is added to the active entities 'FLAT_nnnnnn'
The other selected entities are processed in turn, each edge has its vertices projected onto the plane and a new edge added between them using the original's edge's layer.
If the entity is an group/instance then it is reproduced as a new group inside 'FLAT_nnnnnn', named with its name+"_FLAT".
The layer of the original is reproduced for it.
Its edges are similarly projected onto the plane.
On completion you have anew group in the model called 'FLAT_nnnnnn' containing a 'flat' version of the selected objects edges keeping their layers and grouping.
I'll think about it and come back to you...

Wow. Thank you so much..
I've just downloaded the script.
Again thank you.

Does this script unfold faces?
I've attached the su on the release page.
Thanks and keep up TIG. I'm so Amazed.
