STEP Downloads
 

When I open STEP files downloaded from AndyMark in Inventor, parts in the assembly appear to be unconstrained. Is it necessary to constrain all of the parts or am I missing something here?

Thanks,

Well, if you are using Solidworks. Just don't move the part, but it is importante to constrain the parts if you have time.

Need help IM me.

You're not missing anything. The STEP files contain the location of the parts but not the mechanical relationships between them.

If you want your overall assembly to be functional or realistic, it's best to constrain the parts in the STEP file manually.

You could also ground all the parts in the assembly as a quick solution (that is, make this a subassembly and ground the parts on the subassembly level), but that's more visual than functional since it still doesn't reflect the actual constraints.

Dan -

Thanks for the info. Is there a global ground commend in Invertor or do you have to ground each part individually?

PS 2:58AM??? That is one dedicated roboter

In the SolidWorks assembly, right click in the Feature Manager on the component and select Fix.

If you go to www.3dcontentcentrl.com search for AndyMark. I recreated the AndyMark Chassis by imported the STEP geometry from Andy into a SolidWorks format file through FeatureWorks. These parts are smarter and constrained.

To ground all the parts, just select all of them and check the ground command in the context menu.

Exactly - they can be selected in the view window or in the browser (list of parts) at the left.

Yeah, I realized it's been a while since I visited CD, and the zombies in the hallway were too loud for me to sleep... :)
