How do I get rid of lines on curve?

[jbird68]

Hey,

I have a model of a block. All the curved surfaces have line to show the surfaces. I just want to show th edge lines and not the surface lines. How do I do that?

dispsilh is the key.

yes...i think the value is 1 or 10 i guess

Try 1 or 0, not 10.

 

1=On

0=Off

[jbird68]

dispsilh did not do anything, whether I use 0 or 1.

Try the variable VSOBSCUREDEDGES. Set it to a value of 0. 1=on. 0=off. Does that do the trick?

[jbird68]

VSOBSCUREDEDGES does not seem to be a valid command. When I try that, I get "Press F1 for Help."

AutoCAD settings that affect 3D output.

DISPSILH – Display Sihouette

This setting affects the results of the Hide command. A setting of 0 displays tessellation lines. A setting of 1 suppresses tessellation lines.

FACETRES – Rendered Object Smoothness

This setting affects both rendering and hide results. The default setting is 0.5. The max setting is 10. A lower setting results in a quicker render time but rounded edges will appear as a series of straight segments. A higher setting results in a longer render time but rounded edges will appear much smoother.

ISOLINES – Contour lines per surface

This setting affects the wireframe view but not the Hide or Render commands. Settings can range from 0 to 2047. The default setting is 4.

SPLINESEGS – Segments in a Polyline Curve

This setting controls the number of segments in a polyline curve. The settings range from 0 to 32767 with the default being 8. The higher the setting the smoother the appearance is of a rendered curve.

This is what I am trying to accomplish.

 

 

This was done by previous draftman and put into an assembly. I have tried all settings posted here and still can't get rid of the lines. It looks so much cleaner without the lines.

Let's backtrack.

 

When you reset DISPSILH to 1 did you do a REGEN immediately afterwards?

[JD Mather]

Attach the file here.

[ReMark]

DISPSILH=1 should have worked as originally suggested by JDM. Try again. I tested it myself.

 

[jbird68]

I did regen right after making the change. I have attached the original file.

DISPSILH set to 1. 3DHidden view yields this:

 

[jbird68]

It does not change my view in 3D Hidden. Is there something else that could be set wrong?

Really?

 

I can get it to work and you can't?

 

No, I did not change any other setting.

 

Must be gremlins. Evil creatures they are indeed.

 

Well this is funny. I just reset DISPSILH to 0 and the tesselation lines did not show up. So, I can't get them back and you can't get rid of them!

[ReMark]

Seems like you really don't have to change any settings.

 

I closed your drawing without saving it. I reopened the drawing and went immediately to the isometric view. The visual style listed for the viewport is "Current". I changed this to 3DHidden and the lines that have so concerned you disappeared. That's all it takes.

[jbird68]

I don't see where to change it from "Current" to 3DHidden

Arrrgh!

 

My brain hardly functions well on Monday mornings and you want me to recall the features of of product that is six years old? Do I look like a machine? Don't answer that. LOL

 

What happens if you type the word HIDE at the command line?
