Choosing Default Kernel Type?

[Sam W]

How does one choose which kernel to use as default?

I hadn't given it any mind, looking back seems like I have been using parasolid. Any pro/cons?

It isn’t really too important which kernel you set as default, the important thing to keep in mind is if a shape or command fails in one kernel, try switching the part to the other kernel and try again. The strength is in having two options (like two geometric brains).

It might be useful to set the default kernel before you import a "neutral" STP/STEP file, depending on which system that exported/created the file. The result from the import might differ depending on the default kernel. With "result" I mean if you end up with more or less surface parts or possible topological issues which can be quite common with STEP files.

The fastest way to switch is by clicking on the Properties tab at the bottom left corner and click once in the background ("nothing" selected) and use the drop down menu at the bottom. All new parts created in your scenes will now use this, as this is a global setting and not only for the active scene/file.

 

If you work against//together with a "none Parasolid" kernel based 3D CAD system, then sometimes ACIS might be a better "base kernel" for your models before you export to STEP (or keep the native ACIS *.sat file format to avoid too many conversions between systems).
