Derivation

 

 

 

 

This command allows you to edit a derived part, mirror part, derived assembly or mirror assembly to redefine the entities to inherit.

For example, it is possible to recover the description of the initial element to not have to re-enter it.

 

Creation stages / Use:

 

Select the Tools > Derivations > Derivation... command from the drop-down menu.

 

  1. Select the entities to inherit by checking or unchecking.

  2. For assemblies, also select rigid groups, joints and forces to be derived from the main assembly.

  3. Validate by clicking on .

 

 

The derived part or assembly or the mirror part or assembly has to be opened.

 

 

Available options:

 

 

 

Shapes can be updated automatically or manually.

When a shape needs to be updated, use the Refresh button of TopSolid or right click on the operation (an out-of-date operation will be written in blue in the Operation tree).

 

 

 

Modifications / Additional information:

 

 

Strict:

  • If the mode is checked, the assembly must be perfect. For example, all parts or sub-assemblies of the assembly to derive as mirror must have a part or a mirror assembly, or a plane symmetry or a revolution symmetry). If it is not the case, the mirror assembly will be invalid.

  • If this mode is not checked, the assembly may not be perfect. For example, some parts or sub-assemblies of the assembly to derive as mirror may not  have a part or a mirror assembly, or a plane symmetry or a revolution symmetry). But in this case, the derivation of these parts and sub-assemblies will be ignored.

 

 

Whatever the chosen mode, if the assembly has a local sub-assembly or a local part, its derivative will be invalid.
