Hi everyone, I have some 3D parts (an image of one is attached) and I was wondering if I can export the coordinates of the points making up a 2D cross section of my shape at various Z lengths (because the shape is extruded in the Z direction). for example my extrusion in Z is 10mm and i would like to get the points that make up the perimeter at Z=5mm and Z=2mm. I hope this is clear, I intend to use this coordinates in matlab (a programming software)
Create planar sections at the desired Z values and export the section curves. 2D dxf format for the entities is probably the best option. You will then need an interpreter for MATLAB to read the DXF format.
In the model you generate the section curves by intersecting a plane at the z offset with the solid body of interest (Creo7+). If you are in an earlier Creo build you will need to intersect the solid part geometry when selecting during intersection.
You can then export this closed curve using any csys in the model as an origin for the export.
Example of planar intersect feature (blue curve) with a solid body.
What version of Creo are you working in? I am not clear on your last question, have you successfully created a curve by intersection of a plane with your solid body in your model? Assuming you only have one body in your model, convert it to a construction body. Construction bodies can be excluded in export profiles.
Creo can only export 2D dxf from a drawing so if that is the file format you want to use you must create a drawing with your curves in a drawing view(s).
You can export the curves as STEP from a 3D model and use the csys of choice for the export.
To set a construction body RMB on the body in the model tree and select this option:
The option to exclude construction bodies in an export profile is shown here.
