Recently i had to do some 3D animations / renders on autocad drawings.
Since i didnt have good converter tools, i just asked them to deliver it in obj, or 3ds format.
I dont know exactly how they all did it, from one customer i know he used sketchup pro to convert it.
Anyway what i notice from all those drawing, that every time, they have problems.
Like 3D objects who are not truly 3D, ea missing faces.
Or like with engraved features have separations at unlikely places.
Poorly meshed rounded corners etc, strange triangulations on cylinders with holes etc.
unconnectedvertexes etc, doubles, …
I don’t know how conversion works, but I’m guessing the tools they used don’t invent mesh layouts.
And i wonder how can it be that such files can be used in CAD/CAM applications if they contain that many errors.
Surely autocad should be able to generate drawings with good mesh layouts
So are such errors a result of poor conversions or poor autocad drawing skills, … or ?.
The point is when i give them a time estimation for such a job i can’t really anticipate on the time that i require to fix their drawings, and in some drawings i lost a lot of time with it.
Perhaps there are some tips i should give those people, so that they can send me better meshes ?
