move origin

[Sripri]

Hi, I am sure this question is basic, but I have not done it before and the help is not that useful when I want to get the answer fast to complete a job. 1) In an assembly, I have to move my origin to coincide to one of the parts's origin. 2) If I want to move the origin to any point, how do I do it ? (Similar to of Q1), 3) How do I rotate a part by some angle, with any co-ordinate system in the assembly. I tried the triad method, but that doesn't seem to help a lot for my requirement. I will ask a question about triad in a separate thread. Thanks in advance.

Firstly, you cannot move the origin in a part or assembly. The origin is a fixed point in 3D space. You can however move the features/sketches relative to the origin and move the parts relative to the assy origin.

You can use angle mates to control the rotation of a component in an assy.

I'm with the Limey on this one. If you want to locate a point within a part on the origin in an assembly use mates and control the angular orientation with other angle mates.

you could create a new assembly and insert your assembly (which would now be a subassem0 into this new assembly. Place it by mating the point on this part to the origin and then dictate its angle with angle mates as CBL mentioned

Sripri,

You could also-depending on how your assembly structure is-suppress all the mates on the part that needs to be at the assembly origin, move it to the correct location, fix that part then, correct any mate errors.

This would work the best if all components are built off of each other, rather than each one mated to an assembly feature.

Hope this made since,

Thanks for all the answers. I do have question in the same subject, when I want to rotate a part in a sub-assembly or assembly of few parts, and choose rotate with XYZ option, it chooses the assembly origin and rotates about it. I am not able to choose one of the origins of the parts as reference for rotation which is what I want to do. I referred the help and did not find anything helpful. I used the triad, but the triad does not stay in the place where I leave it last when I come back next time to modify the rotation angle. And also, I am not sure whether I am alighning the triad with the same point everytime. Let me know is there a way to rotate a part in an assembly using one of the origins of a part. Hope I made my question clear. Thanks.

Use the reference planes of the assy and part, or faces of assy and part to create an angle mate.

Select the part you want to rotate, activate the Rotate component command(on the Assembly Command Manager)., and select About Entity from the drop down box in the Property Manager. You can then select the appropriate feature which you want to rotate around.

Above suggestions work very well for my requirement, thanks.
