CAD software is time consuming. Onshape

Find a tutorial on making a mirror copy. You will create a center plane, the plane about what you will mirror your parts, then select the parts and mirror them on the plane.

And a cool thing about this is that it illustrates what’s really happening when you use a mirror. It doesn’t reflect from side to side. It reflects from front (towards mirror) to back (away from the mirror). Looking almost the same when you look into a mirror is about your symmetry, not the mirror’s.

Do you know of any good channels or sources for the tutorial
and thank you for telling me this

Yes I agree, if you find Onshape too confusing, I would recommend using protobot. It is a very easy CAD software to learn.

I was looking at a video and saw that the mirror function is in the part studio and our team’s left side drive train is in assembly so is there another way to do mirror or a way to get my team’s drivetrain onto the part studio because I tried to copy and paste it and it didn’t work

Years ago I had a control knob for CAD. It interfaced via usb. Had multiple functions you could assign to it. It turned left/right, clicked downward, and had some buttons also. Was a big time-saver. Mouse on right hand, button on left.

This is the new/current model of it:

It’s probably outside your budget, but bookmark it. When you get your first engineering job, ask for one.

Never mind I found a way to do it all you have to do is export it then import it back into the document on Onshape as a Part Studio

A problem I ran into is that after I did this to mirror the drive train I wasn’t able to move it around as when it was in the assembly and wasn’t able to fasten any pieces to it I am getting more confused as I keep doing this.

Like should I just stay on assembly and make the other side of the drivetrain as is or should I export then Import it as a part studio to mirror It I am very confused

Less expensive one with only two buttons. I have these connected to every machine I use, and carry a wireless one. They used to be a lot less expensive - I think I bought mine for 40 quid 20 years or so ago? There are always some on ebay second hand for more sensible money. Life in CAD is just different with one of these, but some people don’t get on with them. You need to put some time into adjusting the speeds to suit you, and getting comfortable with it, just as you did when you started using gamepads. Check that the package you’re going to use is actually compatible with it, of course, before spending on it. I use Fusion 360 for my own purposes and it works with all the other desktop apps I find myself in front of. It also works in prusaslicer and 3DFZephyr.

As you have found out, in Onshape you can’t make a mirror image of an assembly with a press of a button. So, for beginning users, I would recommend doing it manually. First, by duplicating the assembly you want to mirror and then making changes to that assembly until you have the mirror image.

But you have almost found a way to create a mirror. You are way ahead! Once you have the mirror in a parts studio, create a new assembly, then insert your mirrored part studio into the assembly. You should now have an assembly that is the mirror.

I did what you told me to do but the parts are not fastened so is there a way to insert it with the parts fastened or do I have to fasten them again?

Try grouping them instead of fastening.
