Question

J-Link: how to determine whether a part is a solid or a surface model

Hi,

In the coming months, we'll probably be importing thousands of models from CoCreate Modeling into Pro/E.

Luckily, CoCreate v.17 allows "save as .neu", which works MUCH better than STEP or IGES, but we noticed that complex models with lots of roundssometimes still result in non-solid models. I'd like to be able to import a large assembly from CoCreate, push a button, and then get a list of all models that are NOT solids. Even better: I'd like all good models to be hidden, and al "wrong" models to be non-hidden 🙂

The only trick I can think of now is to determine the volume of each model (non-solid has value 0), but that will probably take a fair amount of calculation time with a large assy...

Is there a smarter method for this???

Thanks!
Regards,

Jaap

Jaap,
I think your first method of computing the volume might be a good way of
doing it. I know in Pro/TOOLKIT when I retrieve the mass properties
(ProSolidMassPropertyGet) the returned structure contains the volume. It
might not be as slow as you think. However; you are using J-Link which
may be a bit slower than Pro/TOOLKIT.

Hi Patrick,

thanks for your reply! In J-Link it's something similar:

MassProperty masProp = solid.GetMassProperty(null);
Double volume = masProp.GetVolume();

So,time to fire upmy Netbeans and find out...

Kind regards,

Jaap

Yes, it works 🙂

I tried it on an assy with appr. 90 complex plastic parts. Took 30 seconds, so that's appr. 3 models / second.

Nicely reported the surface models with a volume of 0.

Good enough!
Regards,

Jaap
