I am not able to create STL file using STL Rapid prototyping in CATIA.

Steps to replicate.

1. Open an igs file or CAT part file in CATIA.

2. Start - > Machining - > STL Rapid Prototyping

3. Select STL Export

4. Selected the CAD Part for elements.

5. Create file name and click ok



It is saying "No active triangles to export"/

You could just use File + SAVE AS to save the CATIA model in the STL format. But you have no control over the resolution when you do this.


The STL Rapid Prototyping workbench allows you to convert the CATIA model into a tessellated shell of triangles and then build the STL data. Using your steps above, but adding step 2.5:

1. Open an igs file or CATPart file in CATIA.

2. Start - > Machining - > STL Rapid Prototyping

2.5 Using the Tessaltion command, set the SAG and STEP to define the resolution and click OK to make the triangulated shell. (Play around with different values until you get triangles you like. Big triangles will print rough, but tiny triangles will take longer to process)

3. Select STL Export

4. Selected the CAD Part for elements.

5. Create file name and click OK

When doing a file save as .stl,
The resolution is controlled by the display 3d visualization settings.
Tools>options>display>performance>3d accuracy.
