I want to know that is there any command to move part to assembly origin.
As an example,
As you see in attach photo,
part origin and assembly origin is different.
I want to move part origin to assembly origin.
There's no picture attached?
Assuming you modeled the part, you simply turn on the datum planes and/or the coordinate system and use them as reference to locate your part with respect to them.
If you are using a "start part" it should have coordinate system or datum plane, if not, you can create default coordinate system and default datums before making any other features.
Ahh, that in assembly...for the first component, you can use the "default" constraint
Where it says automatic, change that to default. That will make your coordinate systems coincident.
Then look through tutorials for assembly to learn all the other options.
