Cyan Lines on Projected Geometry on a Curved Surface

[vishnumaiea]

So I was trying to project a feature to a curved surface that is not aligned to any axes. I created the feature by making a tangent plane (tangent to the target surface) and creating a sketch on it. I was able to project this feature onto the surface, but when finished, the sketch appears as cyan colored lines instead of a rectangular face that I could push-pull.

Projecting to surface

Image 1 : Projecting feature to surface

Image 2 : No new face created on the projected surface.

If someone could shine some light on this, that would be appreciated.

Split Face 

or Patch and Thicken

Hi,

Instead of split face and press/pull you can use the extrusion tool.

1. Extrude from object

2. offset > Extrusion to object

depending on how the surface should look.

Ah! That worked. Thanks. Still, do you know what the cyan lines mean?

[vishnumaiea]

But here, the extrusion created doesn't follow the radial path of the curved surface.

Thanks for the reply anyway 🙂

But by creating a patch and thickening it, we can.

I would be concerned about this.

Can you File>Export and then Attach your *.f3d file here for diagnosis?

[vishnumaiea]

Yeah, that's an artefact created when I used the extrusion tool. Only noticed it now. It was due to a bad sketch profile. I corrected it in the timeline.

Unfortunately, I can't share the design file.

Hi,

It also works without plane and sketch.
try it this way:

Nice. Will keep in mind ✌️
