1. Open the model for which you want to clean shape geometry files.
2. Click the Applications & components button in the side pane to open the Applications & components catalog.
3. Search for the Shape cleaner application, then double-click to open it.

   The Shape cleaner dialog opens.

4. Select the shapes that you want to clean.
5. If you need to hide unnecessary edges or show more edges in the selected shapes, use the Edge visibility settings.

   

   1. Enter a threshold value for the angle between the neighboring faces in each of the selected shapes.
   2. To hide edges when the neighboring shape faces are in a smaller angle than the threshold value, select the first checkbox.
   3. To show edges when the neighboring shape faces are in a greater angle than the threshold value, select the second checkbox.

   Shapes with too many visible or invisible edges can affect how various Tekla Structures features operate on items that are created using those shapes. For example, creating rebar sets might fail if complex shapes have too many edges visible.

6. To create backups of the shape geometry files, select Create backups from shapes before cleaning.

   Creating backups of the original shape geometry files allows you to restore them if needed.

7. Click Clean.

   Tekla Structures cleans the shapes and shows how many shapes resulted in being solid objects and how many non-solid.

   If you need to interrupt the cleaning process, you can click Stop.

8. To see the changed shape geometry in the items in the model, close the model, then open it again.

If you have created backup files, you can restore the original shape geometry files if you are not happy with the result of the cleaning.

1. Open the Shape cleaner dialog again.
2. Select the shapes that you want to restore.
3. Click Revert.
