problem with 3D
problem with 3D
(OP)
hello,
I'm a trainee in a company, and my job is to design a bridge.
I'm french, so please excuse me if I make mistakes in english
I did a solid for the all bridge, now I would like to divide this solid into different solids for different materials.
The form is quite complexe ( it is not cubic)
I selected a face of my solid and I extruded it to figure the first wall, but now, autocad doesn't recognize my draw as a solid, so I can't continue.
I could I make it a solid again?
or do you know a solution to begin again from the draw of yesterday ( not the last saved)
thanks a lot for your help

AutoCAD will automatically delete the polyline unless you
SETVAR <CR> DELOBJ <CR> 0 <CR>,
which I suggest that you do when starting any new drawing. The reason is that when you explode a solid, AutoCAD decomposes it into REGIONs, but it doesn't reconstruct the original polylines, which you need to reconstruct the solid.
When you build the bridge over again, don't make it one big solid and then try to separate it by material. Use different layers for different materials as you build it. Even for components that are of the same material, resist the temptation to UNION them until you can't avoid it.
