Importing dxf files from Strata 3D
-
An OBJ export > SUp-import [using one of the free OBJ-importers] will preserve any 'textures' ... but when it's in DXF format it probably won't ?
What is it you want to get into your SKP - just the geometry or the geometry+textures ? -

Hi Frithioff,
did you try to export the model directly from Strata as DXF or Obj? For me it works fine.
CharlyI tried to import 3-d objects directly from Strata dxf and 2-d planes in dxf in order to extrude.
Perhaps it has to do with the dxf reader preferences. I show the used ones. And the bad result in SU.

A very simple example: how can I extrude figure in the attached file?
-
If any object [like a facet] is very small [<~1mm] then SUp has a problem making it, so try using smaller units for the DXF export and larger units for the DXF import [options on the SUp dialog] - So mm >> m say.
You can always rescale stuff in the SKP later - very small facets can exist in a SKP... but it's the initial making of them that has problems... -
OK, so I got the below dxf file (zipped) from Fit (somehow he ended up with a PM) and imported it to SU and there is some interesting result there...
zero-one-blend-1 copy outline.dxf.zip
-
Imported at 'meters' the outlines are pretty scrappy and although they'll take faces the edges are not draw well or consistently...
It would be easier to import an image and trace over it...

However since I do not use Illustrator, it would be best to post these on the open forums, not in private messages so that others with more experience with the program can help better.It is a very simple file, just for this purpose. Made in Illustrator, exported to dxf. But if it looks good to you - just tell me how to extrude it, so it becomes 3-dimensional...

Okay, first: the whole import comes in as a component. First right click on it and explode.
Then zoom in and redraw a line segment from endpoint to endpoint.
Now you end up with the shapes filled - however the hole in the letters is also filled.
There will be some clean-up needed here and there as you have double lines around these holes.
Once you clean up and separate the faces in the holes, you can right click > Erase them and then simply use the PushPull tool to extrude them.
In SketchUp, there is a 3D Text tool. Would that not be easier to draw your letters with?

If you have a decent 'black and white' image of this text then why not save it as a PNG with the background fully transparent [no anti-aliasing].
Import that PNG into your SKP as an Image.
If you want it as a physical object [make it a reasonable size, you can always rescale things later] then use my ImageTrimmer tool [search the Plugins Index] which will cut out the forms automatically - end by choosing a simplify of ~2 so that the smooth curves get replicated and pixel-jaggedness is avoided.
You then have a component with geometry faces and the original material applied to them.
You can edit them using PushPull etc as desired........
