Inserting Openings, Holes, Drilled Holes in Solids
Tips & Tricks
Inserting holes in surfaces has become very easy due to a wide variety of options. You can use these options also for solids. However, you need to keep in mind that an opening at the beginning and the end of a continuous hole must be created, as well as a surface that separates the hole from the solids. In order to complete the modeling quickly and effectively, the following procedure is possible.
As an example, there is a single splice modeled with an opening initially added to the top side. Since it is always convenient to have several surfaces on the periphery of a rotated surface, you can add a line and split the circle into two semicircles using the tool ‘Connect Lines/Members’.
Then you can select all elements related to the opening (the semicircles and the opening) and copy them using the ‘Move/Copy’ command. There you can use a boundary line as the displacement vector. In order to define the internal surfaces of the hole, you can select the ‘Surfaces between lines’ option in the details of the ‘Move/Copy’ function. Finally, the new additional surfaces must be included in the definition of the solid.
