How to change the position and attitude of my stl model?

Asked by jimtianxi on 2012-02-24

I often use the software Pro/E to draw my tool, and save the model in .stl format. When I import the .stl model into yade, I can only use the function yade.ymport.stl(), but this function doesn't include the members 'shift' and 'orientation', I don't know how to change the position and attitude of my model. Please help me, thank you!

Hi,

it seems, stl-import really does not support such operations.
The "quick" solution can be to load your stl-file into the GMSH and
then export it to "MESH"-format.

Then you can import your geometry using yade.ymport.gmsh() [1], which
supports shifting, scaling and rotation of imported geometry.

Thank you for your answer! But what's your meaning of 'quick' solution? Is it a software or an order in yade? How can I get it? Please teach me further in detail. Thank you!

gmsh is a separate software.
If you use something from Debian-based, just:

sudo apt-get install gmsh

Then open your stl-file with this program and save it as mesh.
You can do it even from a command-line, just read the manual.
