For parts that you create by picking only one point (such as columns), you can define the top and bottom level of the part in the global z direction. The part is created at the defined level, not at the level you picked in the model. This can be useful when creating multi-story structures, as you can define exact levels for each part you create.

1. Create a part that requires you to pick only one point.

   For example, a column.

2. Double-click the part to open the part properties.
3. Go to the Position settings area.
4. Modify the top and bottom levels of the part.

   • Top: Use to define the top level of the part.

   • Bottom: Use to define the bottom level of the part.

5. Click Modify.
