Selecting an Area between Two Bodies

Anonymous — Mon, 21 Jan 2019 01:33:30 GMT

I've been trying to select an area between two bodies on a sketch to extrude, but can't seem to find how to do it. Below I have included pictures of the bodies and sketch I am referring to. One of the isometrics is of what I have now and the second is a picture of what I want. The sketch shows what I want to be extruded. Thanks!

If you had attached your file to the thread, it would have been easier to show you.

However:

Start a new sketch on the top of the rings.

Project the ring body to the sketch.

Extend the ring segments to make full circles:

Select the area to be removed.

Use Extrude|Cut to remove it.

The four segments in the intended pic, should work for you,

because, the actual pic, shows the whole ring, it seems to me that the sketch has not been cut into segments, but if that were the case, then you could not show the intended pic, so there is something in that catch22 missing.

If you have projected the four outer rings to the Extrude sketch it should work as expected.

Might help....

When I extrude the sketch it extrudes the whole circle. Below is an image of what it looks like right before extrusion.

Attach your file to the thread (Create the file from the file menu: File|Export|Archive file *.f3d).

Have you tried the method I showed in my previous post?

Can you show me on the file? I'm not familiar with projecting. I just started using this software.

So that means the profile sketch you have does not contain the referenced crossing lines, that @etfrench mentioned. You Extrude sketch needs those crossing lines in it.

project the two bodies, that will cut that sketch profile into three major bits, Extrude one, then either project the other two bodies into the sketch, or circular pattern the single web.

Might help....

Here's a screencast showing the project technique:

Your model could be more efficiently done with fewer sketches and no moves (Moves should be avoided as much as possible. Use joints to position components). Attached is one way to reduce the model to two sketches. Use the arrows at the bottom left of the Fusion 360 window to walk through the creation of the model.

p.s. See Rule #1

p.s.p.s. Please show us a picture of the completed drone.

Sheesh @etfrench that was a lot of work.

@matthewfriend99 all you need to do is:

1. Delete that last Extruded operation.

2. Edit that last Sketch.

3. In that sketch, you've already got one circle. Project in the others so that the one you've got will be divided in the right places.

4. End the Sketch.

5. Do the Extrude, selecting only those divided areas that you desire.

What can I say, I like drones My screencast shows an easy way. The file shows a better way.
