question regarding projection of the edge of a cylinder and sweep cut

question regarding projection of the edge of a cylinder and sweep cut

question regarding projection of the edge of a cylinder and sweep cut

(OP)
Hi all,

I have two questions when doing the experiments,

1. i try to let the vertical line be coincident with the edge of the cylinder (see picture 1), i tried to use project curve command but no result...

2. in the swept dialog, thre is an option called preserve shape (picture 2), I notice if i check it, the shape of the cross section will be EXACTLY the same as the sketch, OTHWRWISE, the swept shape will be a little different, am i correct?


3. i actually want to cut the sweep, as previous member suggested me to expand all options in dialog to see there is one can do my job. i didnt find it. is there any option to do sweep cut if I dont like to add another substraction step to finish my need?

thank you all

RE: question regarding projection of the edge of a cylinder and sweep cut

  1. Try using the intersect curve command within the sketch. Pick the cylindrical surface to intersect with, change the resulting curve to reference and constrain your other geometry to it.
  2. The swept command will approximate your sections with splines. Overall, splines do a great job at this; however, one thing they don't do well is approximating sharp corners. If your input section(s) have sharp corners that you need to maintain, turn on the preserve shape option. If the sections are tangent continuous or you don't need to keep the corners sharp, you won't need to use it.
  3. When you expand the dialog settings, there should be a "boolean option". The one you want is "subtract". Alternatively, there are advantages to be had in creating the solid and subtracting it in a later feature. This gives you the opportunity to perform other operations on the solid such as adding draft, blends, trims, etc before subtracting from the target solid.
