Create oarts in an assembly

[Mark.Lancaster]

I’m sure this question has been posted before…

When creating a new part in an assembly and I select a face of an existing component, how does Inventor determine the orientation and origin of that new part?   I understand how Inventor works when I select the plane/origin of a part or pick out in space in the assembly…   But the placement based on the face of an existing component seems random..

I normally do not like creating parts inside of an assembly but I was trying some new workflows.

I'm not entirely sure how it's placing the origin - I know it flushes a plane to the face you decided to make it on.

I can only warn against making parts in assemblies without being careful. If you project geometry from the assembly, you'll create an adaptive part.

Having adaptive parts that are adaptive to other adaptive parts, and so on, will make it hard for inventor to calculate as well, so be careful.

When I make a part in an assembly the first thing I do is Mate the remaining origin plane DOF to the part I am modeling against (or to the assembly origin planes).

The default is X-Y with the extrusion being in the Z direction unless you have changed the defaults for "Part" in the Application Options. This is the same for Sheetmetal as well.
