Edit Part Structure

Right-click part > Part/assembly structure

You use the Part structure functions to edit main part and sub-part structures. The following functions are available:

• Move part, Subordinate to active part
• Move part, Convert into main part
• Delete, Break up sub-part levels
• Delete, Active part, without sub-parts
• Delete, All sub-parts

---

Move part, Subordinate to active part

Right-click part > Part/assembly structure > Subordinate to active part

This function assigns to the active part an arbitrary part of the drawing as a sub-part. Identify the part that you want to assign as a sub-part to the active part. 

Before: Assembly 1 is active	Right-click Assembly 1, select function, then select Part4 as part to be subordinated	Assembly 1 after execution of function

---

Move part, Convert into main part

Right-click part > Part/assembly structure > Convert into main part

This function converts the active part to a main part, removing it from the previously superordinate main part. If the part belonged to a main assembly, it will be located on the same level as the main assembly afterwards.

Assembly 1 is active	After execution of the function, Assembly 1 becomes a main part on the same level as the main assembly

---

Delete, Break up sub-part levels

Right-click part > Part/assembly structure > Break up sub-part levels

Simplify > Break up sub-part levels

The part structure of the selected part/assembly will be broken up.

If all parts are of the same type, e.g. only solids, the parts will be unioned via Boolean operation. The part name will be the name of the selected part.

Assembly1 is active and contains only solids	After execution of the function, Assembly 1 is a solid, and all parts of the assembly were unioned via Boolean operation

 

If the part / assembly contains different sub-part types, e.g. solids, parts with free surfaces, parts with free edges etc., all sub-parts of the same type will be unioned into one part via Boolean operation. The name of this sub-part will be the name of the selected part, followed by an automatically assigned number.

Assembly 2 is active and contains different part types	After execution of the function, Assembly 2 is a dummy part and contains the parts of the same type, unioned via Boolean operation

 

This function can also be found on the Simplify tab. If the function is called from there, multiple selections of parts/assemblies are possible.

(1) Original structure, (2) Multiple selection, (3) Structure after breaking up of sub-part levels

 

Please note:

• Special cases are parts or assemblies that have only one sub-part with a "genuine" geometry, i.e. surfaces, curves or isolated points. If you execute the Break up sub-part levels function here, the subordinate part replaces the part or assembly to be broken up. The following data of the part or assembly to be broken up will be taken over in the process:
• Unambiguous body identifier,
• Referencing property,
• HELiOS properties (see settings in the Configuration Editor at System settings > Referencing > Attribute synchronization),
• Fitting coordinate system and
• Feature attribute of the body.

• Other special cases are planar sketches: Here, only the sketches which are located on the same plane will be unioned. I.e. in this case, more that one sub-part may be generated.

Delete, Active part without sub-parts

Right-click part > Part/assembly structure > Active part without sub-parts

Here, the active part will be deleted, but its sub-parts will be preserved and will be set one level higher in the structure.

Before: Assembly1 is active	After: Assembly1 is deleted, and the sub-parts of the assembly are set one level higher in the structure

---

Delete, All sub-parts

Right-click part > Part/assembly structure > All sub-parts

All sub-parts to the active part will be deleted.
