    Default Reduce size of imported 3d Sketch Up files

    Hi evryone

    I've exported some 3D files from Sketch Up into Autocad. That worked quite well so far. The problem now is, that the files are around 1 - 7 MB and too big to move around on my current drawing.
    Even when I xref it into the drawing it is impossible to do anything with it as it constantly keeps on loading the object.

    Is there any way of reducing the size of the file? Also is it possible to remove all the lines of the faces? For example a car has lots of faces because of the bent surfaces and it ends up looking completely grey as you can just see the lines.

    Hope someone can help me with that.

    Cheers, lilith

    In a nutshell, I create 3D models from the client's CAD files or design sketches which I then use to produce high quality rendered images. Click on the link in my signature to view my portfolio. I'm always looking for work, so let me know if you need any custom models or renders. :)

    I think this is more of a Sketchup question than an Autocad question, so I have moved your question to the Sketchup section.

    Check these links for some ideas on how to reduce your file size before exporting:

    Do these models have lots of curved faces? If so then this is the problem. SketchUp can do curves like AutoCAD. It simulates curves with faceted edges and faces. Anytime you create more edges and faces you increase file size.

    Once in a while I will get a sketch up file here at my work, and I have the same problem. The only thing that I have been able to do with the files is to re-draw them as solids vs. the faces that sketch up does. It can be a bit of a pain, depending on the shapes in the drawing, but in the end it saves time in several areas. Such as loading, creating presentation drawings, or modifing the drawings.

    Wow, I go completely the other direction. I will do easy stuff in SU and complex/curved items in Acad (or other) and then bring into SU for presentations.
