Editing a Part in a Union

Modify an item in a union. The union may contain multiple multi-level unions. Parts inside unions can be edited directly, for example, changing the height of a cuboid. When more complex editing is required (setting properties on faces), the part should be copied out, edited and placed back into the union.

  1. In the model tree, find the relevant union that you want to edit.
  2. Under the union, select the part that you want to edit.
  3. From the right-click context menu, select Copy (duplicate).
  4. Edit the duplicated part.
  5. In the model tree, drag the modified part back into the union of Step 2.
  6. From the right-click context menu, select Replace.
    You can replace a part with a completely different part. For example, replace a cuboid with a flare or sphere.
