Section style does not work?

My job is to understand everything about Rhino, Grasshopper & Revit, which i fall rather short in accomplishing.

rajaa is the developer of section tools. Profile - rajaa - McNeel Forum

Ideally you could create individual threads with clear examples of the issues and we can work though them.

There must be at least a few team members working on the sections and section styles. If it’s just a single person it’s too much. I understand the section tools might be related to section styles, but from the user’s perspective, the section tools are really their own thing and used to create 2D geometry based on the section cut.

The things that aren’t working in R8 have actually brought my projects to a complete halt. So for me it’s pretty serious. I’m even contemplating downgrading to Rhino 7 because whatever is wrong it’s breaking stuff that worked in R7 as well.

That was my response to this question in particular, there are a lot of developers involved, Rajaa is the primary dev in this regard, but any youtracks created get assigned accordingly per their subsystem.

Are there any particular youtracks that you are waiting on? If applicable i’ll bump up the priority.

For me the most essential things are:

(I’m using the word section below often referring to
Clipping plane which I think is a misnomer)

1 - make all geometry that is in the section plane visible / selectable. As it is today, you can draw a line and when it’s done, it disappears, because the Display Pipeline is not working. Just that simple bug renders drawing in section useless.
Same with hatches, that frequently disappear if they are in the section plane (which is where they are supposed to be)

2 - make an option to outline the full geometry when selected in section mode. As it is now, when manipulating an object which is partly cut by a section plane, you have no idea what you are doing, because you don’t know how the full object looks. This is a major drawback and simple to fix.

3 - selecting thing while in section mode is really buggy. When picking surfaces it’s impossible to understand which surface is being selected. I’ll post a small animation of this tomorrow.

4 - also those hidden command for enabling and disabling all sections are not working well. I select two section planes and click the Perspective section tickbox. I then disable all section planes. That works. When I enable all of them again it enables other section planes on hidden and locked layers. So to
Make this work I need to go through loads of section planes looking for checked tickboxes. I need to do a save a layer state, turn everything on, select all clipping planes, destroy their settings… We need a way of going in and out of section mode smoothly. I use it over and over again to work in complex geometry.

5 - please do a section mode where we can see both sectioned geometry and what has been cutaway. In two different display modes. So cutaways in light grey wireframe and rest in rendered. Or whatever.

6 - this is more tricky but very important - make
all linework created by the section plane act as ā€œrealā€ linework does! So you can click on a line (created by the section plane - it does not exist as an object per se) and you can copy it, or extend it or extrude it, or use the gimbal on it. As soon as such an operation is performed the manipulated section geometry becomes a real rhino object.

There are more important points. I will fill in more tomorrow as I work in the section/clipping plane. As an architect it is used almost all the time. Those points above would simplify a lot. Save hours every day.

Thanks

Hi Erik, Here are some of the Feature requests. The others we need to work through a bit more (3, 4, & 6).

RH-86778 Add Hatches to Clipping Plane Display Mode Settings

Clipping Plane Option to Override Object Section Style. (Display mode could still override the override)

RH-86779 Clipping Plane Option to Override Object Section Style

RH-86779 Clipping Plane Option to Override Object Section Style

RH-86883 Option to allow selected Section geometry to be visible

RH-86884 Section Display Mode that shows sectioned objects differently

How shall I help out ?

Hello,

Is the feature shown in the image at the link still in use? I think it’s no longer active. I hope it’s my mistake.https://docs.mcneel.com/rhino/8/help/en-us/commands/clippingplane.htm#ExportClippingSectionInfo

Command-line options

UseClippingPlaneDepth

Extracts the slices using the custom depth set in Clipping Plane properties as the thickness.

  • When the custom depth is disabled, 0 is used as the thickness.

  • UseClippingPlaneDepth=Yes hides the Thickness and Location options.

Thickness

Specifies the slice thickness.

If the thickness is 0, planar slices are returned. Otherwise, 3D solids are returned.

Location

The location of the slice relative to the clipping plane.

Front

Creates the slice in front of the clipping widget.

The triangles point to the front direction.

Center

Creates the slice with the clipping widget on the center plane.

Back

Creates the slice behind the clipping widget.

Group

Specifies whether output objects will be grouped.

Hi Heycey -

The ExtractClippingSlices seems to work as expected here.
If you have a sample where that is not the case, please provide both a 3dm file that we can examine and the output from the Rhino SystemInfo command.

Hello,

I’m sorry, but I can’t upload anything due to company rules. However, after the last update, the problem resolved itself.

Another question I have about this tool is: Can we use the intersection points of two clipping planes during visualization? Not for cutting or slicing, but only for visualization. I mean limiting the clipping plane’s area of effect in a parallel direction, not in depth. I would love to explain it visually, but it’s not possible.

Best regards.

Hi Heycey -

That feature request is on the list as RH-3952 Clipping Objects

It’s an old topic. I hope it will be considered worth developing and made available for use.

Thank you!
