Surface Modelling Expert Required! 1

[SiW979]

Hello People

I have been helping some sponsored undergraduates on a project where they have to design, build and race a soap box cart. They also want to some CFD on the CAD model to analyze the aerodynamics.

Anyway I'm no surfacing expert (as you can probably tell by the attached model) and what I was hoping for once I had sewn all the surfaces together was sheet solid as I have had on many other models in the past. As you can see by this model however, it is still just a sheet body and not a sheet solid. Please could anyone tell me where I have dropped a clod as I can't find it.

Many thanks in advance.

Best regards

Try Analysis -> Examine Geometry and make Sheet Boundaries the only box checked, then window select the entire part. This will show you where any holes may be that prevent a solid from forming. (Thanks to nkwheelguy for giving me that advice a few years ago)

Simon,

A critique of your surface would be somewhat cruel as I know you don't lay claim to any real expertise in this regard. If you contact me I'm happy to knock up a more suitable example by implementing a few simple changes to the method and surface break-up in that model.

In the meantime the quick an easy fix for that model is to change Studio Surface (27) to degree 5. Having done so you'll simply find that you need to delete and re-apply the final sew in order for it to output a solid body.

I would of course welcome any advice or tips, I'm never adverse to learning something new. The more I learn the better!

Hi simon,

I always keep the 'confirm upon apply' checked while sewing sheets becasue after applying I get a chance to see all those holes or irregularities and also all analysis options.
