Good morning all.
For new projects i decided to try Proview. Seems the beauty comes from inside.
Like always, there is not enough time, to solve everything 'trial and error' style, so my question is, are there howto manuals to help me benefit from all the prebuilt components? What object has to be put where, and which attribute has to be connected to what structure?
Thanks, Stefan.

Stefan,
You have great courage. The best way is to jump in at the deep end, after you have read the manuals thouroughly.
I took an existing class (BaseMValve) and modified it a bit to suit myself. I made it into a BaseAircylinder. Everything stayed the same only the names and the pictures changed. It gave me a reasonable insight into what is required and at the same time it was quite impossible to make great booboos since ultimately nothing changed.
Doing a little exercise like that will give you enough feel so that you dont misjudge the time needed to learn the system once you are going to do a project.

Have fun,

Jan
