How from 3D stl make flat 2d dxf


#1

Hello,
I got following problem.

I have downloaded from thingiverse nice 3d shape - I would like to make from it nice 2D - dxf file - or just 2d shadow in sketch up.

I have tried to meke qube - and run over the 3d shape - and than erase it - but it does not work.

Can you help me.

First, explode the 3D Text object. Then do the following:

Almost working -no I can select flat surface - but it is flat and I can move it away - and it is not one surface.

I would like to make strictly shadow projection of component.

It is not extruded :frowning:

I think we’re having language issues–I’m not too sure what you’re saying.

Why not just show us what you’ve got–either a screen shot or the model itself.

Ok :smile:

Let’s try:)

Model is here and I am able to select bottom surface [
and I am able to make the group - and move it away - but how to remove the lines inside - and have only contour - and export this to flat .dxf

If by “lines inside” you mean the edges of the individual flat facets that form the 3D contour (they look like zig-zags), you don’t “remove them” because the model depends on those edges to bound the faces. Instead, you Soften/Smooth them.

Yes - that’s it ! almost

problem is that this surface is not flat - so whot I need is shadow projection - and completly flat 2D out of this -

Or you can edit the group and use the eraser tool to delete those edges.
Or you can use the plugin CleanUp (Thomthom) for a one click solution.

Or you can use a section cut in the middle of the object and the “create group from slice” context menu option…


#9

you can do this with dxf export settings, using the original model…

post the link to the model…
