Solid modeling vs surface modeling

[bbrannerud]

When you start on a new project, how do you choose between making a surface or solid modeling? in surface you can add thicken and in solid you can add shell?

So how to you use to decide witch way to go?

(also do you know any good tutorial series in creo parametric witch take on both advanced and simple modeling?)

I only use surfaces if I am doing a stylized part.

Normally, my parts are machined or sheet metal, where solids are simple.

I consider surfaces "construction geometry".

I mostly use surfaces for my work. A couple of main reasons are:

1. Complex surfaces to capture ID intent

2. Lighter skeletons, to ease referencing (via copy geometry)

3. Easier visibility(hide/unhide) manipulation, mainly by using layering

The good thing is whatever we need to do on solids, we are able to accomplish it surface modeling. It may require more steps (such as shelling) but it's still possible.

Hope this helps.

woops I saw now that i accidentally made two posts. this text should have been here also:

If we would for example model this:

A drone would you make its chassi in solid or surface and why?

The same with this helicopter propeller blades?
