Reply To: Matching One Object’s Origin to Another (Specifically the Rotation)

Well, If you have that placeholder Cube (and in the set-up you said you have several placeholder Objects), then you can use the above described method:

With the placeholder selected, create a new Transform Orientation by clicking the +.

Then import the Cube,  which comes in like this:

Check Affect Only Origins and SHIFT+ Select the Placeholder and then SHIFT+S > Selection to Active:

Then switch to Placeholder Orientation and with the imported Object selected, go to: Object > Transform > Align to Transform orientation. The result:

That seems to work. Please let me know if I still misunderstood, or didn’t explain well enough.
