Create cutout in a circular thin wall body from an imported sketch

lsnyman — Thu, 30 Sep 2021 17:30:43 GMT

I am a total newbie trying to learn fusion 360. I get how to create a cutout in a body by sketching on that body, but I have a specific sketch that I need to use as a cutout template to cut into a thin wall cylinder body. I need to repeat the cut 8 times evenly spaced around the cylinder.

I have the sketch on the primary plane but cannot figure out how to use it as a cutout template.

Any help is appreciated

Hi,

EMBOSS is your friend

Turn on your Capture Design History.

Make sure that your sketch is on one of the two planes on the axis of your cylinder (or in a plane Tangent to the cylinder).

Subtle difference between Emboss and Extrude.

I think this is a lot easier if you move it to one of the other planes parallel with the cylinder axis.

Here's my screencast, file's attached. You might want to edit the sketch and position more accurately, this is easy now history's been enabled.

@HughesTooling One more question. I applied your tutorial and got the same result. However when you applied the 1 emboss, the result was cut through but when you applied the 8 circular pattern the visual only showed the embossed outlines not holes anymore and when I export the model for 3d printing, there are no holes.

What am I missing?

If you watch the screencast again you'll see I only set the depth to -1.0mm, I didn't know you wanted them cut through.

And this is after the pattern, there are pockets not just outlines.

No it works with faces and will be more efficient than features.

Got it, However in my file when I try using faces, it says the selected objects is 110 vs yours at 1. Am I selecting the wrong thing?

The V2 file you attached doesn't have any history for the emboss, did you disable history then re-enable?

Even though it asks for Faces you can select a feature from the timeline and only the faces that feature created will be selected.

This time it worked. I was missing selecting the emboss feature in the timeline, I was selecting the face on the drawing and it kept failing.

This is not very intuitive. Thank you though for taking the time to help.
