Ok so while recreating the chassis i noticed that inventor pro isnt giving the same dimensions for one line every single time… Does somebody have the EXACT dimensions for the cassis? Just need width/length on a side view and top view… No holes or anything special. I may just abandon this project. Its proving too complicated to get the right dimensions ;(@Daniel_Noree ?)
Maybe you could import the Stl-files in 123d design. It’s free from autocad and easy to measure with
@Abc_Def I’ll get you a drawing with dimensions in a bit.
@Daniel_Noree thanks that will help alot. Just need the general dimensions and the dimensions for the holes where the bulkhead attaches
@Daniel_Noree thanks. Im guessing that this is in mm? And the hole pattern is the same front and rear? us in america are the odd one out. We normally dont use metric. But we can 
@Abc_Def yepp, everything is in mm. The Holmes are The same in the front.
