Lofting on an angled plane

Lofting on an angled plane

Anonymous
Not applicable

Hello everyone, 

I'm a student at Cookeville High School, in an engineering class. I am reverse engineering a pair of clamps, and have come across a lofting problem when creating the grip. I have a plane angled to the degree that I need, and a sketch on it that I want to loft to. For some reason, I'm not allowed to loft to the plane. I noticed, though, that to create an angled plane you have to rotate it on an existing line, on an existing plane. Would I need to move the new plane's location, or some other unknown to me method of accomplishing this. Thanks in advance.

You can Loft it in 2 sections. The top 2 sketches for the angled part. Then make 'Sketch 8' visible and Loft the rest of the sketches. ('Sketch 2' has an open loop. Edit the sketch right click select 'Sketch Doctor' keep hitting ok/next and that will fix it.

You should state when you are not using the latest release - or you might get solutions that you cannot open.

 

You should download and install the latest Service Packs and Updates for your version of Inventor.

 

I tell my students to test each sketch profile before attempting to Loft by trying to Extrude.

If a profile won't Extrude - there is something wrong in the profile.

 

Running the Extrude test on Sketch 2 reveals that it is not properly closed loop.

I insist that my students dimension all of their sketches.

 

If I turn on all Constraints I see that it is missing a Coincident constraint and Tangent constraint(s).

If I dimension the geometry - I see that it is perfect?

Why would someone create perfect geometry and then delete the dimensions?

 

I see two R10 arcs where one would suffice?

I also found a missing Horizontal constraint?

Nearly all of this work - Inventor will do it for you, so it is actually more work to do it "wrong".
