Make translucent curves on a certain

Can objects such as lines, curves (no surfaces, just vector lines etc) be made translucent for just one layer.

I was given method for objects as in surfaces some time ago.


Display mode can be overridden on a “ByObject” basis, not a “ByLayer” basis.
Use SetObjectDisplayMode

Here is a box in a Shaded display viewport, with a red box set to display in Ghosted:

Hi, I have just 'curves, others call them lines !

no objects as with surfaces, and wish these ‘lines’ to be translucent.

As I draw them on the current layer, each new line must go translucent, if not, then I wil settle for selecting them all then making them translucent.
Allocate them to a layer called translucent lines I want them to be translucent when on that layer. So much so that altering a slider I can make them almost disappear.

No surfaces involved.


What are you trying to achieve by making lines translucent??

I do not believe what you are trying to do is possible based on the display settings

You could try a “hack” where you turn the grid off and you set the curve lines to be the same shade of grey as the background or a slightly darker/ lighter version of it but you cannot physically make the curves translucent


Hi, I am tracing over a not so well defined picture and find the strong lines, even using light grey, are blinding me regards seeing the subtle detail I am following.


How about making the pictureframe transparent and move it above the cplane so lines drawn fall behind it?
In the past I have successfully used that trick for the situation you describe.

You will need to make a new material that has the pictureframe’s image as texture. The material can be set to a desired transparency. Next assign the material to the picture frame. If you use SetObjectDisplayMode on the pictureframe to be rendered curves behind it will show through.

This…except there shouldn’t be any need to reassign material textures to the pictureframe. Just adjust the basic settings transparency.
