Clean up from superfluous features

When you have completed the design of a part or reached a certain state you may want to clean up or in other words, erase superfluous features. This can be done by using the menu Tools>Delete Useless Elements. Before you execute this function, it is important, that you understand, what is looked upon as "Useless".

If you simply select the menu Tools>Delete Useless Elements and confirm the panel all features are erased, accept those who are parents to any solid features. All features, which have been referenced by creating a solid features are protected, from the bottom to the top of the Parent/Children chains. If axis systems are included in the file, they will then however be erased.
The elements, which are going to be deleted are highlighted in the list and in the geometry.

Panel

When you select the  menu Tools>Delete Useless Elements a panel is displayed and the result from the automatic scanning is presented. All elements (features/axis systems ...) are listed and there is an informative text, telling what will happen with the element, e.g. Keep solid, Keep, used by solid, Delete.
At the panel bottom a summary of the interaction is displayed, e.g.16elements: 4deleted 12kept. If you change the conditions the list and text are automatically updated.

Change the conditions

By using the context menu in the list, you can change the conditions. If an element has been assigned the operation delete in the list, the entry can be selected and thereafter the context menu Keep. This element will now be protected and also all its parents.

Example

The surface has been designed and it shall be kept with all its parents and the second axis system. There is no existing solid feature.

1. The menu is selected Tools>Delete Useless Elements
2. The final surface feature is selected with the context menu Keep
3. The second axis system is selected with the context menu Keep
4. The summary is checked before the panel confirmation
