Hi all,
would be possible to have “backgroud” curves in separate layer by using Make2D command with clipping plane? As “ClippingPlaneIntersections” or “Tangents”
I think as by ClippingSection - there is “backgroud” as separate layer. By using Make2D are backgroud curve just in “Visible-curves”.
If you need separate layers, why not use ClippingDrawings command instead?
Hello @rajaa
this command create separate layer with sublayers for each clipping plane/section - sorry, but this is not userfriendly solution.
Everytime and for all new drawing i must setup all layers properties (colore, print colore, linetype…) around and around…this is not usuable.
I was looking forward for Cliping section commnads, but for serious drawing work are unusuable…unfortunately 
Make2D create one time layers for Make2D - just for first time and every next use place outputs curves in this layers.
When will be possible to define “hard” constat layers for Clipping Drawings - then will be this command usable. Or pre-define just properties of all new sublayers (f.e. “all clipping intersection are black and 0.35 width”…etc..)
This is why i still using Make2D instead ClippingDrawings…
@Chita I take your point.
Will this request report satisfy your requirement?
thank you, this would be greate!
If I understand you right, those are already separated: section curves are under “Curve” sublayer while background curves are under “Visible”. Is that what you’re asking for?
Hi @rajaa ,
yes, but “visible” in front elevation and “visible” in section bacground are diferent things.
F.e. In drawings are elevation lines in thick black line, but visible lines behind section are faint gray lines…
Background lines should be Visible and Hidden too….but in technical drawings man not see “invisible” lines behind “plane of cut” (respectively, it is not drawn)
edit: SEC_01 is not cutting the object are front of 3D geometry…
Something like this:
Or just have in “section layers” only one layer for hidden lines - i think should be enaught…
There is no separate concept of Elevation→Visible vs Section→Background→Visible.
Elevation curves are are treated as being in the background with Visible and Hidden curves. If you need visible background curves to be thicker, you need to set the “Visible” layer to a thicker curves. That will apply for visible lines in sections as well
Yes, but this is not user friendly too much… would be great little improvement in the future in Rhino 9, to make this feature better and usuable for faster work….
In this time is this feature “nice but not effective” because not respected rulles of technical drawing in all steps…. unfortunately…
Let me make sure I understand. You would like another layer in the template that is “Elevation Visible” and is used when the clipping plane does not cut through objects?
Hello @rajaa ,
Yes, something like this….”Elevation” name was just example for this… There is important to have “visible” and “hidden” sublayers under “Elevation”..
Please test the next WIP. The layer naming will not change, but if the clipping-plane is not sectioning through objects, the “Background” sublayer “Visible” will take the properties from the new “ Elevation Visible ” layer in the Template.
Hello @rajaa ,
this look greate! Thank you very much for this improvement!
Hi Dušan -
Can you please post a simple 3dm file that clearly shows the distinction between those two states?
At the moment, I’m making up things, but we might as well try to get this right?

Hi @wim ,
yes, below i am sending simple 3D file.
Point is - if man need drawing that respect the rules of technical drawing - need difrence between “Elevation visible line” (front view without clipp…) / “Intersect with CP line” / “Lines behind intersect” - those lines have diference print width at least.
And my next question is related to this - would be possible to have not just “clipping plane” but “clipping polyplane”? Just use extruded polyline or curve for clipping….?

Hi Dušan -
Thanks. That confirmed my understanding for the request.
If that part of the comment refers to a hidden line that is drawn as visible in the file you posted, when I deleted the clipping plane and created a new clipping plane in the same place, that line was no longer generated. If you have a way of reproducing that from scratch in a current build of the Rhino WIP, please let us know.
That request has been on the list for a while:

Hi Dušan -
Almost 23 year ago, you mean…

First time 13 years ago….OK, i will keep waiting
