Sweep along feature edge

I am trying to sweep a profile along a feature edge. In this instance, the sweep feature will function, however the sweep is not consistent, meaning the sweep profile does not maintain itself perpendicular to the surface edge.

Notice the left edge where the sweep profile begins is perpendicular. Towards the right, the sweep profile is tilted about 20 degrees. How can I create a sweep along an entire surface edge while maintaining perpendicular to the surface edge?

Attach the file here.

Does it work if you use a guide surface?

What about using the Lip command instead?

In this model, the sweep along curve with guide surface works.

However, the model that I'm working on looks more like the one shown below. Including a draft angle of 10 degrees, not 45 degrees. The sweep feature fails.

I'm not familiar with the Lip command. Is this feature included in Inventor LT?

3d Sketch is no longer needed for Sweep (r2012)

Did you use the xz plane for your guide surface?

Have you installed Service Pack1?

I understand a 3d sketch is not needed, but when I select the feature edge as the curve, the sweep feature transforms the edge into a 3d sketch. This is typical right? I'm using Inventor LT 2012

 

I'm not sure if I have service pack 1 installed. Is this listed under Options?

Image above shows successful build after updating to Service Pack 1. (Although I'm not quite sure if this was already installed.)

Capture13.jpg

When adding the additional features I need such as placement for a screw hole, the sweep becomes more problematic and won't build correctly using Sweep along curve with guide surface.

The result is shown above, notice the right side of the sweep is tilted inwards.

I couldn't reproduce the tilt after I added a screw hole placement to your Part1.ipt.

Please post your model with the screw hole placement.

 

Thanks,

The sweep will not build using a guide surface. The result is still tilted inwards.
