ghost line in Sketch Task Environment

Genius

The scene below:

 

  • in sketch task environment of "SKETCH_000"
  • The blue curve is the spline "002".
  • "SKETCH_000" is on the plane of the spline "002".

 

Zooming shows a ghost line under the blue line. It's odd. Why? Thanks!

Hi @GaneshKadole

 

I only knew "Update Display" is unavailable in Sketch Task Environment. Thanks for letting me know "Regenerate Work" is usable!

 

I can understand the case of two connected lines displayed as be unconnected due to tessellation.

 

I'm still curious about why there are a solid line and a phantom at the position of a single spline object. Maybe this is related to certain NX mechanism of handling splines?

If you hover over the line to get the "quick pick" dialog, what does it show?

Hi @Ken_A

 

Only one object is there. No "quick pick" dialog. Thanks!

Is that dashed line a constraint indicator?  like a point on line?

Hi @DaveK

 

When the grey reference line is deleted, the ghost line dissappears also! But in the sketch there are only two Conincident contraints on the end points. The ghost line under the blue spline is still difficult to understand.

 

Thanks!

Hi @surfactant,

 

Your reference curve in your sketch is constrainted to the spline, which is outside of the sketch.  I suspect that by constraining your reference curve to the spline, that the sketch needs a copy of the spline in the sketch (the ghost line), in the background the system is likely using the Project Curve sketch command (in fact, if you open your sketch, choose "Project Curve" and select Spline 002, you'll see that the projected curve lies on top of the ghost curve).

 

Hope that helps.

Regards, Ben

Hi @BenBroad

 

Your guess is very reasonable.

 

Yet as shown below, the projected curve (light blue) lies on top of the spline (dark blue), not the ghost curve (highlighted).

 

Thanks!
