Set Scene to Parasolid Kernel before Exporting

[Malcolm Crowe]

Historically we have used the Parasolid kernel by default, but recently we have been using the ACIS kernel, as we have been exchanging models with other ACIS based CAD software. We have discovered that this change in kernels within the 3D Scene has affected the structure of our exported files. The ACIS kernel doesn't convey any of the assembly structure of the original model. It will only convey parts. What we have discovered is that when we export STEP files (which are supposed to convey the assembly structure), if the kernel of the IRONCAD Scene is set to the ACIS kernel, then the assembly structure isn't conveyed in the exported STEP file. However, if the IRONCAD Scene is set to the Parasolid kernel then the assembly structure is exported as expected.

Attached are images of the following Scene Browsers:

1. The original IRONCAD Scene

2. The imported STP AP214 File from ACIS Scene (parts only, no assembly structure)

3. The imported STP AP214 File from Parasolid Scene (correct assembly structure, although reordered)

So the tip is, to ensure that the IRONCAD Scene is set to the Parasolid kernel before exporting, if you want the assembly structure to be exported as well. Simply selecting STEP isn't enough.

When importing STEP files, set the scene to use the Parasolid kernel; and in the STEP import options check the "Source for Part Name".

See the link below if part names aren't being imported as expected. The "Source" may need to be set to "Definition".

I don't know when this changed, but IRONCAD now exports and imports the assembly structure correctly within a STEP file regardless of the scene kernel selected.
