What 3D program to use to create objects?

[matchy]

If you are looking into modeling arrows and such (according to you question on another post), you may do better using an online tool or even model it straight inside glbasic.

Your suggestion that I build vector arrows directly inside glbasic is what I trying right now. The advantage is that no .ddd files would be required, everything being contained in the code.

We've been through this before. No attempt to post any 3D code on the forum, so there's really no reasoning in recommending 3D apps.
