How to add Sketch Elements without disturbing my Extrusions

k_w214k_w214 Member Posts: 3 EDU
Hello

I have a part that I want to edit

I wish to add some sketch elements (shapes) to an existing sketch and then add new extrusions from them
However, when I add new elements, Onshape does its own " Guesswork " about the new element and screws up all the original extrusions. 

For example, i might add a circle to an existing sketch, and onshape automatically makes a hole through the part

How can I add new sketch elements without onshape automatically altering extrusions from the sketch

Best Regards

    Edit the extrude and select the hole that is created to add it to the extrude definition.

    Yes, that would be what I am doing right now, 

    - Edit sketch
    - Go through all my extrusions to fix Onshape's automatic changes

    Wondering if there is a way to disable the automatic changes?
    It gets really bad if i divide up a square into two parts, then Onshape will only extrude one random part.

    Thanks for the answers everyone. 

    I will keep Onshape's boolean logic in mind as it flips between filled and cut areas

    Generally, adding new sketches seems to be a cleaner way to editing a complex part
