Creating a Ground plane/Precise Rotation of an Assembly

Anonymous — Sun, 15 Dec 2019 18:39:53 GMT

Hi there Autodesk community. I am reaching out for assistance in our school's Formula car design. I am struggling on figuring out how to precisely rotate/place our car model with the ground clearance numbers I have. There are two points on the chassis. The front point will have a distance of 4.0 inches from the ground. The rear point will have a distance of 4.5 inches from the ground. I have an assembly file of many parts.

My question is: How do I create an appropriate ground plane for the car and precisely rotate the chassis such that these 2 points meet their specification? I had tried creating an offset plane but I wasn't able to figure out (if even possible) how to constrain these points with these distances.

I am using Autodesk Inventor Professional 2020

Hello @Anonymous,

I am not quite sure if there is way to control ground plane associate to geometries.

Reaching out to project team right now.

Keep you update once for any feedback.

Why not just constrain the points off of one of the origin planes at the correct distances?

Attach your file(s) here and end all doubt.

(What you want to do is easy - if I understand the problem description.)

Hi! You may want to use UCS to do this. In the top-level assembly, insert a UCS at 0, 0, 0, coinciding the origin. Now you can constrain your components to the workgeometry in the UCS. If you need to move the whole thing, you can move or rotate the UCS. The components should move with it. Is this what you were looking for?

Many thanks!
