Hello,

I’ve come across a few bugs in Rhino 8 (RH8 SR9) related to the section tool. I’ve compiled a list of them in one post to keep the forum organized.

Thank you for addressing these. Perhaps there’s a setting I’m overlooking.

  1. Section Drawings -

    1. Geometry below and above not displaying correctly.
    2. Not cutting through blocks correctly
    3. Editing section drawings after placement command makes drawing disappear - Redo
    4. Hatches often only visible in wireframe mode

  2. Section drawings | Placement point -

    1. What is the exact position of the placement point relative to geometry?
    2. Odd placement point location

  3. Relocating section drawing - unlocked layers revert back to previous position after update

Geometry below and above not displaying correctly.

Hi, sorry it took a while to get back to you. I was on vacation and missed your message.
Can you please share an example that I can test with. Also, please try the latest service release and let me know if that works better for you.

To answer your questions:

Geometry below and above not displaying correctly.
Not sure I understand. Can you share a small 3dm example file?

Not cutting through blocks correctly
It should work. Can you please share a small 3dm example file?

Editing section drawings after placement command makes drawing disappear - Redo
How are you exactly editing?

Hatches often only visible in wireframe mode
Can you please give a 3dm example file?

What is the exact position of the placement point relative to geometry?
The placement point is the center of the section.

Odd placement point location
When you add or modify the geometry in your model, the placement point is saved in the section to help align updated section exactly on top of the old ones.

Relocating section drawing - unlocked layers revert back to previous position after update
You should use use EditClippingDrawings to change placement of a section. Unlocking and replacing manually does not change the placement point saved in the section

Hi Raja,

Thank you.

Geometry below and above not displaying correctly.
Not sure I understand. Can you share a small 3dm example file?

Please see the attached file. The horizontal section facing downward (floor below) is simultaneously displaying the floor above section, which it should not. For example, walls in the upper floor.

Not cutting through blocks correctly
It should work. Can you please share a small 3dm example file?

Unfortunately, it doesn’t. I have placed the blocks within revision clouds.

Editing section drawings after placement command makes drawing disappear - Redo
How are you exactly editing?

Using commands to edit the clipping drawing and then the placement point, if the command is executed and you press Ctrl+Z, the drawing disappears entirely. You need then create completely new section drawing.

Hatches often only visible in wireframe mode
Can you please give a 3dm example file?
Please find attached

What is the exact position of the placement point relative to geometry?
The placement point is the center of the section.

The issue arises when I reference a DWG site drawing of a city section. The reference point is located at a great distance. Even though I disable the XREFs layers, the point persists, including the entire DWG.

Odd placement point location
When you add or modify the geometry in your model, the placement point is saved in the section to help align updated section exactly on top of the old ones.

I understand, but I’m unable to precisely align the floor plans and sections because the placement point varies in different locations.
