How to Convert
3D Models into STL Files
CATIA
forward Select STL command (we recommend setting maximum segmentation to 0.015 mm)
forward Select the model > Yes > Export
Note: CATIA V5 software is used for converting catpart to stl files, so it converts catpart to stl files, but not from assemblies (CATProduct files) or geometrical representations (car files). Therefore, source files, including those saved in a neutral format (i.e. STEP or IGES), must be saved as CATParts. If the source design was saved as an assembly, it is imported to CATIA as a CATProduct. To create an STL file from it, you must first convert it to a multi-bodied part. The procedure described below is one of several methods for doing this.
STL files can be saved - with the special add on module. catia V5 is capable of creating & converting catpart to stl files from parts(catia PARATS files), not from assemblies (catia product files) or geometrical representation(car files). Therefore, source files, include those saved in a neutral format (STEP OR IGES ,for example)must be saved as parts.
Saving CATProduct files as CATPart Files for 3D printing:
forward File Menu > Open > select your source file (assemblies import as CATProduct)
forward
Save the imported CATProduct file
forward
Select File > New > Part > Name the new part
forward
Select one component from your master CATProduct File and copy it
forward
Paste the component in a new part window
forward
Repeat steps and until you have copied all of the components and pasted them as individual parts
forward
Once you have the assembly completely separate into individual components, select File > New Part
forward
Copy each of the individual components from the working files and paste them into the new combined model file (the geometries of all of the parts should retain and align correctly in the combined part)
forward
The new part is now ready to be exported as an STL file
forward
Select Tools > Generate CATPart from Product
forward
Finally, Select File > Salve As > Save as type: STL
Tip: Occasionally some of the components may not align correctly in the combined part because of the way the original assembly was designed. To align parts, select Insert Menu > Constraints Feature.
Tip: Curves’ accuracy ratio: The higher the setting, the smoother the surface will be when dealing with complex geometries, especially if surfaces contain sudden small changes with small radii (like the bumps on a golf ball).
Before saving the file, it is advisable to review the settings that determine model accuracy and file size. To see these parameters:
forward Tools > Options
forward
Under the general category (on the left), select display
forward
Select File > New > Part > Name the new part
forward
Review 3D Accuracy settings
