Section style does not work?

@erik6

are you in charge of the section tools in Rhino?

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.

Please read this if you are logging a bug or issue

If you are reporting a bug, it helps to: Check if you are running the latest Service Release Make a single topic for each issue Run _SystemInfo in Rhino and paste the result in the topic. Send in a sample file that shows the issue whenever possible, even if it appears to happen ‘always’. Provide step by step instructions how to reproduce the issue This allows us to help you faster and will make it easier to log and track bugs Thanks in advance for your help!

rajaa is the developer of section tools

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 “real” 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)

@erik6

1 - make all geometry that is in the section plane visible / selectable.

How shall I help out ?
