Editing a hole

If the solids are created as basic shapes (box, cylinder, hole etc), you can edit them very easily by modification of their spatial dimensions, as shown in this example.

Copying the shape

Select copying the shape to copy the exact shape of the right hole to the left hole.

Selecting a hole and groove for transformation

If you need to change the position of any basic parts creating 3D object, switch the object selection to select the single elements or to select the branches of Boolean tree. In this example, the hole and groove are selected as single objects.

Another possibility is to select single elements from a list of Boolean tree scheme. Between commands, you can also press and hold Ctrl key and move cursor over solid’s elements. Then, elements instead of entire solids are detected. Select element (or elements), finish selection by right-click and then choose command to edit (transformation, delete…).

Transformation of the objects

After selection of a solid’s part for transformation, the original shapes (in this example the tool creating the hole and the tool creating the groove) are displayed and you can define a new location. After confirmation, the objects are moved to the new location.

For transforming parts of solid, you can use also a respective option of the function “Edit solids”. The edit function allows you to transform only sub objects from one solid at once and allows you to change shapes, too. The function “Solid transformation” used here allows you to transform entire parts as well as their sub parts at once, but does not allow changes of shapes.

Selecting parts of the solid to be deleted

If you need to delete any part or parts of the solid, switch the object selection to select single elements or to select branches of Boolean tree. The groove and the chamfer of the edge are selected to be deleted in this example. The chamfered edge will be rounded in the next steps.
