Inventor: Sweep a rectangular tube at a 90 deg angle

[Anonymous]

I am trying to make a swept rectangular tube at a 90 deg angle. I have the dimensions that are needed and the arc, but the bottom face isn't coming out flush (See attached). Any suggestions? or do I over shoot and then cut with an extrusion?

Your arc is NOT 90°?

Sketch2 is not fully defined?

Is your Profile sketch Perpendicular to your Path?

Attach your *.ipt file here.

The center of the radius is not dimension and floating in space.  Is your sketch fully constrained or does it require "X" number of dimensions.

From what I can see, as Mark and JD posted, your sketch is not constrained.

I can see that the bottom end of the vertical edge is based off the sketch X0Y0Z0 point, I can only assume the vertical line of the edge is constrained vertically.

What is the distance from this vertical edge to the center of the radius in the X and Y direction? Adding those constraints would constrain the radius and most likely fix your issue.

No offense but why do so many user not constrain their sketches? I see it all the time. It's Sketching 101. But I digress.

Hi @Anonymous,

Could you please attach the files here?

We need to have a look at the part, in order to provide some solutions for you.

Hi! I think the only logical reason to explaining the behavior is that the profile plane is not normal to the path at the end point. If it was, the profile projection on the right should pass the center point of the arc.

1) Simply move EOP above Sketch2.

2) Create a normal to path workplane by selecting the end point of the arc and the arc itself.

3) Move EOP to the bottom.

4) Right-click on Sketch2 -> Redefine -> pick the newly created workplane.

Now, the Sweep will work as desired.

Many thanks!
