I am saving assemblies as VRML and taking them into crossroads and saving them as 3DS files for import into a program called Floorplan 3d.
When I bring them in, I need to specifiy the size of the object.
Is there something that will tell me the overall dimensions of an assembly in Solidworks, as in X Y Z???
Thanks, Devin
Devin,
Indirectly you can use Mass Properties and approximate your building as a box. Mass Props gives you Moment of Inertia about the x, y and z axis.
All Moments of Inertia's are a combination of width, base, height.
Engineering.com has the formula's for moment about the x axis and centroidal x axis. Note their orientation for the Origin is not the same as SolidWorks.
I like the centroidal x axis because it is easier to solve 3 equations and 3 unknowns with less fractions.
Example: IX = (m/12) (a^2 + c^2), SolidWorks labels this value Px.
You could use a density of 1.
Note, this ia an approximation and depends on the complexity of the model. It may be more appropriate to use a cylindrical shape or compound methods.

Thanks, if that's the easiest way, I think I'll stick to measuring it manually.
