Re: 3d PDF importieren

Hallo, gibt es eine möglichkeit 3D PDF zu importieren? 3D PDF gibt es in zwei Varianten. Erstens im Universal 3D-Format (die ältere Variante) oder im PRC-Format . U3D ist ausschliesslich Polygonnetz. PRC Polygonnetz oder B-Rep-Daten. Einzig B-Rep würde sinnvoll sein. Da die Urheber der PDF meist Ih...

Re: glTF format support?

As long as FreeCAD has no native export, one of these methods: I created a wiki page to document this: gITF Is there anyway to import gITF in to FC yet, using a workaround? Use OCC 7.5 ;) There is support for reading and writing glTF 2.0 The name implies only writing but here it is mentioned occt a...

Re: Exporting Multiple Meshes to one STL...

... This is only partially true. STL-Ascii can describe multiple solids, STL-Binary not. But most programms ignore this. It works like this I don't know if this is officially supported. At least the article on WP does not mention it that an ASCII STL can have several objects: https://en.wikipedia.o...

Re: Exporting Multiple Meshes to one STL...

This is odd. I have no problems exporting multiple objects in a single STL file and Cura opens it and shows the objects spaced as I had them in FreeCAD. I've actually been doing this for quite a while. I simply select the objects and then do File->Export as an STL file. I think OP wanted to have th...

Re: Exporting Multiple Meshes to one STL...

And the further problem with trying to use Mesh export for this purpose is the fact that it is ghosted and can't be reached when multiple meshes are selected... and I don't see an 'add/append mesh to file' button so... :cry: Yes, thats true. But you are able to save it with File -> Export obj. That...

That is strange. I tried it and I get 3 independent Meshes in Blender with the obj-file.

Re: Exporting Multiple Meshes to one STL...

... As the file format doesn't support separate solids, there is nothing FreeCAD can do about it. This is only partially true. You quoted only partially. As mentioned in my post, FreeCAD uses the binary format; so ASCII-stl would be a new export format. Mesh Workbench Mesh Export also offers Ascii-...

Re: Can't create solid because shape is not a shell

The cylinders are connected if according to CREO 4.0 because I was doing the model using that software and then import into FreeCAD. According the obj-file (freecad export) they are not connected. They touch and intersect, but they are not connected with the main object. See screenshot from Blender...
