How do I put a multiple holes in a circular pattern on a cylinder

I am struggling with adding multiple holes around the outside of a cylinder. The circular pattern only lets you work on the plane you are sketching. Is there a way to have a hole applied to the outside but using the circular pattern on a plane normal to the circle?

    May I ask what program or app you used to create that animated GIF?

    Couldn't you save a few steps by making a blind hole with the hole tool then using the circular pattern tool?


    Also wanted to mention for anyone else searching out how to do this, the circular tool is not located in dropdown menu as part of the pattern tool.

    For Gif recorders see https://forum.onshape.com/discussion/comment/13813#Comment_13813


    I haven't tried but I would have done the same as @shanshan because unless it changed recently the pattern tool doesn't accept features.

    Does anyone know how to use the hole tool to make a circular pattern around a spherical object? I can do this using the method posted by shan in the above post. But I've been trying to use the hole tool to create a circular pattern:

    daniel_chow, please click "face pattern" in the dialog box of "Circular pattern", and choose all the faces of the hole in "entities to pattern"!in your model ,the hole depth is too big ,that's why you could not pattern the hole, please check it !

    Thank you Shan it worked!

    And for anyone else searching up how to do this, be sure to check out this onShape tutorial on making a pipe flange
    https://www.onshape.com/cad-blog/lets-make-a-pipe-flange

    You'll use the revolve feature to draw a round object, then use the circular pattern tool to patter a hole around the flat surface of the flange. This tutorial will only take < 10 min drawing the model from scratch. It offers a third way of using the pattern tool different from the two method discussed above.

    One trick you can do when doing a face pattern of holes is to use the "Create selection..." tool on the context menu.  With the hole option selected, the system tries to infer the hole based on a single face selected.  This way you should be able to get all faces of the hole.

    1. Right click on the canvas and choose 'Create selection...'


    2. In the 'Create selection' tool, click the drop down and choose 'Hole'.  This will try to infer a hole based on the faces selected.


    3. Select one of the faces of the hole.  Notice that the rest of the faces should highlight as well.


    4.  Click 'Add selection'.  Notice that your one selection has now put in four selections in the circular pattern dialog.
