Creating a new sub-assembly within an assembly

Anonymous — Wed, 13 Apr 2016 11:08:37 GMT

In Solidworks, if you insert some components into an assembly, you can select them in the tree, right click and choose "Create new subassembly here" (or something simiar) and it will create a subassembly of the parts, within the main assembly.

As per image below. I think Parts C and D need to be constrained only to each other and Part B, not to anything in the main assembly but I can't remember for sure.

Is there an equivalent command in Inventor?

Thanks

Hi,

Try Demote command.
Right click -> Component -> Demote

Thanks,
Jaroslav

As Jaroslav mentioned, Demote should do what you want.

Demote ...but MAKE SURE YOU HIT SAVE ....

you'll need to save the main assembly file ...so you can save the new sub-assembly file in it.

You'll be asked to to do an Initial Save in the pop up box

Thank you all for the replies. That's great.

I see in the video in the dialogue box where you create the new subassembly it refers to it as an in-place "component". By "component", does it mean subassembly? I.e. a subassembly that once saved could be inserted into another assembly, and has no link to the original parent assembly in which it was created?

Many thanks again

Correct ... it's what Inventor just calls it ...

You'll keep almost all constraints too ... if something is set up in the Main assembly it won't transfer to the sub, but if 2 parts in the sub assembly are constrainted together, they will transfer into the new sub assembly you setup.

I really like the Demote/Promote command. I think it's one of those commands/tools that could be used more if people knew more about it ...

Thanks again.

Yeah, it's really handy. I'm using it to model a frame to support a pipework system. It allows me to build the frame within the main assembly, so I can make sure all the supports are in the right place in relation to the pipework, then I can end up with the frame as its own subassembly.

The main component of the frame located in the main assembly with three constraints, and then all subsequent components of the frame are constained only to other components of the frame, and not to the main assembly.

It's probably not used because "demote" is a terrible name for what the command is actually doing. Not intuitive at all. "Create subassembly from parts" is the intent, so that's what the name of the command should be.
