How do I do multiple distance mates in Onshape?

asyraf_saaet

I'm trying to mate a specific part on a base plate where the precise distance from the datum is key. Therefore, I'll have to use 3 mates to lock it in place. On the plane is easy but for the X and Y is not as clear cut as in Solidworks.

You will be able to accomplish what you describe with one Fastened mate between mate connectors.  In Fastened dialog, click offset and enter the x,y values.  OR create mates at the locations required in part studio.  see the attached picture and OS help Mates - https://cad.onshape.com/help/#mate.htm?Highlight=mates

@asyraf_saaet, Yes you can do it by giving mate constraint with respect to two / three faces with the help of planer offset. kindly refer below video for more detail.

@asyraf_saaet, If you want to supply an offset distance, check Offset and supply a distance. Fastened mates can offset the entities along any combination of the three axes:

Offsetting entities from one another during assembly is available for the following mate types:

• Planar offset - Along the Z axis
• Slider offset - Along the X and Y axes
• Revolute offset - Along the Z axis
• Pin slot offset - Along the Z axis
• Fastened offset - Along the X, Y, and Z axes

You can also drag the entities and observe the distance values in the graphics area. These can help determine the specific values to enter in the dialog.

Please refer below video for more detail.

Thanks guys. But what if I want to mate the part in X direction from face 1, and Y direction from face 2. Is there anyway I still can do that?
