Making modifications to derived parts - a question for cabinet builders

patrick_reid742

Hello, I am making my first cabinet in Onshape and loving it; however, I think I am doing certain things the hard way (duplicating, replicating, etc.). I am hoping there is a better way to do the drawers. Currently I have a part studio for almost every drawer but many features are the same across all of them, like drawer slide cutouts, bottom panels, width. The drawers on the left and right are the same except that the drawer face is offset different directions. I am pretty sure derived parts are the key but am wondering if I can just make one "master drawer" and then adjust things like the face and height on the derived ones? Is this possible, or what is the most efficient way to create many different drawers based off one main design? Thanks for any help.

You should learn about configurations…

Looks like you would only need to make your drawer once if you used a few variables and configurations (or even configurations variables)…

Have you looked at 'configurations' to build the drawers? Making each one in its own part studio is a lot more work. With configurations, common geometry is used by all drawers with a selection of items that vary like length width and height being selectable or entered on the fly.

When inserted into an assembly you can be queried for size by a selection or the dimensions can be asked for.

You can't configure a sketch contraint…
However you could draw it centered and use a transform to move the body sideways "up to" the relevant sketch point/reference.

This sounds like the answer I am looking for. I will learn about configurations. Thanks

Configurations is very cool but there is one thing I can't find. How do I change specific constraints in a configuration? In my case, I want the dimension of the left drawer face to reference the left edge and the configuration for the right drawer to reference the right edge.

Once you do a deep dive into "suppression", this will add another layer to configurations, that you should explore. Each config. can have any number of features shown or suppressed. This can become as complex as you want to make it, so it is literally impossible to describe all of the combinations that are possible (let your imagination be your guide). Extremely powerful tool though (be sure to look into this).
