Clipping plane shows points outside of clipping range

Hi all -

I think this is a bug?

I’m using a clipping plane with a set depth (LOVE this feature of R8). It does a great job clipping away most of the geometry (point clouds, surfaces, curves), but for some reason, points that sit behind the clipping plane are still visible. Surface control points show the same behavior.

On the attached images, I would expect to see only the green point, as it sits on the same plane as the clipping plane. In the clipped view one can still see the red point, along with the two surface control points that sit well behind the clipping plane.

In my demo example this isn’t a big issue, but I have models with dozens of points behind the clipping plan, and the whole point is to not see them… :slight_smile:

It is a bug. I just worked on a fix yesterday. You should see this fix in 8.12 which we will start shipping release candidates for in a couple weeks.

Hi Steve - perfect timing :slight_smile: Enjoy the weekend.

can you include one neccessary thing which is to display intersection of clipped curves as points? i cannot display my curves which are perpendicular to the view in any reasonable way.

From Rhino 6 and up until Rhino 8.9, lines that were head-on in a parallel view were not visible. This was changed in Rhino 8.10 to the Rhino 5 behavior. As far as I can tell in a quick test here, a clipped line is also visible.

In this picture, the view in the floating viewport is not clipped, the one in the viewport underneath is.

it would be great if it was like you say but i cant see it

in layout

in pdf i see no dots

wim you are partially correct. it is visible in raster mode in pdf. but raster is out of question for technical drawings. curves are not visible in vector mode nor in raster mode when clipping plane has depth set on. i am going to make a new topic about this. this is absolutely crucial for my workflow and definitely for many others.

I see what you are reporting and will try to work on it this week

please see my specific topic about this i described it in more detail
