How to place an angled hole through a pad

Post by BoeingTechGuy »

I am trying to place a 0.4375" Dia. hole through a .75" pad. The hole is to be at a 15 degree angle from the base of the pad to the top of the pad. I have tried to search this forum for something that details this, but I see no direction. I am a newbie at the use of FreeCad and any help would be greatly appreciated. Thanks

The attached file is one way of doing what I think you are trying to accomplish:

The steps are as follows:
1. Select the face from which you want to Pocket (drill) the hole. Place a draft on that face at the angle of the inclined hole.

2. Select the draft face and mount a Sketch. Locate the hole with respect to the global axis or with respect to the edges of the block. Pocket the hole.

3. Mount a Sketch on the side face. Create a rectangle large enough to remove the draft with a Pocket. Locate a corner of the rectangle to be coincident with the original block by using Create an Edge Linked to External Geometry.

Alternatives:
* Boolean cut with an angled cylinder in Part workbench (a padded sketch will do, you'll need to rotate the sketch).
* loft between two circles made on two faces. Note that the hole will have an elliptic cross-section in this case.

Maybe you need a special feature, go into Macros_recipes and Code_snippets, Topological_data_scripting.
