Delete a Solid Body

mkoenig1 — Mon, 18 Apr 2016 02:23:13 GMT

When using the Delete Face command with the Select Lump or Void option on a multi-body part to delete a "solid body", the "lump" still shows in the Solid Bodies node of the Model browser after being deleted. I've checked and there are no mass properties or faces on that body. The part is still showing as a multi-body part. Is this a limitation of the software or is there another way to delete a solid body?

Thanks,

Michael

The body node exists in the tree because it exists in the history of the part.

To remove it, you could use the combein command to join the two bodies together or go back in time (roll the EOP market up) and prevent the body being created in the first place!

This only applies to the body in the feature tree. You'll still need to deal with the geometry.

Post your part for more specific workflow help.

to Paul from Autodesk: Why can't you guys make deleting parts easier, I need to make them invisible, best solution but by far really bad. If I need to see only one part, I make all others invisible then I need to make a note of which one was the bad part I need to keep invisible. this makes no sense. just make it possible to delete a part. how hard can it be?

The purpose of this tool is to delete a solid in terms of closed geometry, not in terms of a history element.

This is a linguistic problem, because both of these states have the same name, but by definition they describe completely different phenomena.

This is best seen when, for example, you have a solid composed of many geometrical bodies. Graphically they are separate bodies, but historically they are one solid.

P.S. You can always rename the solid.

To sum up - this tool in the solid mode removes the closed spaces of the model in the geometric sense, not solids in the sense of managing its structure and history of the model.

@constantin_dancu

It all works in a logical, completely predictable and robust way for me.

Attach your file so that the experts here can diagnose the logic of what you have.

Hi @constantin_dancu Please could you clarify?

A 'lump' is a set of connected faces which does not connect to anything else (also known as a 'shell').
A 'body' can contain many 'lumps'. It has a separate node in the part file.
A Part is a separate file, which is bought into an assembly file. It has a separate node in the assembly file.

To delete a 'Lump', you can use the 'delete face' with 'lump or void' option checked, or you can use the direct edit command. However, it may be better to use the end of part marker to roll up the feature tree, and make adjustments so that the Lump isn't built in the first place!

To delete a body, delete all the features that belong to it - or edit the features so that they belong to other bodies. You can use the 'delete faces' or 'Direct edit' commands to delete a body, but (as @mkoenig1 the OP mentioned) this won't delete bodies from the model history.

To delete a part from an assembly - right-click and choose 'Delete'. This won't delete the file on disk, it will only delete the part reference from the assembly model.

Does this help?

As @JDMather suggested, please feel free to give us some more detail about your workflow and we can advise which option is best for you.
