Combine parts to make a single part from multiple parts

will_brett_atkin

How do you create a single part from multiple parts in OnShape? I have two relatively complex parts that I want to combine into one part that have been imported from solidworks. I don't want to have to remodel either parts 

The parts need to become one part as the part is intended for 3d printing. 

Thanks

Union in Boolean feature will help you to combine multiple parts as a one part. See the below GIF animation

@will_brett_atkin, You can get your desired result by performing Boolean union (merge parts) operation.

please refer below example for more detail for combining 8 different parts.

1. Click .

   

2. Confirm that Union is selected.
3. Click to set the focus in the Tools field, then click all of the parts (small cylinders and larger cylinder).
4. Click .

   

Note: First selected part appearance will be final resultant part appearance.

If the parts are in different tabs you will need to get them into 1 part studio before performing the Union. Use the derive feature second icon from the end in the Part Studio toolbar to do this.

Amazing thank you everyone for your great responses.

I have a "part" with .sldprt extension but when I put it into an assembly and move it, it comes to pieces. I've tried to do the boolean union, but it says "cannot resolve entities". Even without this problem, there are many internal parts that will be hard to select as shown in these examples. Is there a rubber band, select all function?

Group the parts in the assembly, then they will behave as one. Try grouping stationary stuff and then group those components that move. In the end you'll have fewer mate connectors relating those things that move relative to those that don't. This is to help keep the assembly organized and manageable. This works well especially as your project grows in size and more parts/assemblies get added to the top assembly.

There are many new ways to handle parts in an assembly which will confuse you if coming from SW. In the end it's going to help when your project gets larger and more complicated. 

Add to the mix, configuration management, using the built in PDM; you'll be able to control release states and access that larger organizations are interested in.

This ain't SW, and that's a good thing,

Great answers so far, I have a similar problem but with meshes.

I intend to 3d-print "remixes" where I only have .STL-files of something and want to combine those with my own constructions and/or other STLs. An imported STL gives me a mesh that I can only place, and possibly resize (haven't tried because measurements would be off for my purpose).

The boole union feature in this case won't let me select the mesh, only my own constructed parts.

What am I missing to make those one single part?

@magnus_hammar, aside from simple scaling, I doubt OS will be able to edit meshes any time soon. If a feature doesn't have to do with machine design, it's not likely to be improved. For now I would use something more suited to editing STL files, like MeshLab or Blender.
