Clipping plane which view to draw in to hide these parts?

Hi,
I never get it right first second or even third time, why is Clipping Plane not intuitive ?
my blue line shows the slice and view direction I want.
I want to hide the items left of the blue line, so that in ‘LEFT’ view I get a clear view of the circular parts of the brake drum.
In my brain I see a need of a plane sitting in the ‘left’ view, surely thats where the plane would be, sitting between the wheel and the support arm from the chassis.

If I draw it there I dont get the drum revealed.

Just which ortho view does one draw it in, please use my jpg to draw it in.

then as I silde it to and fro I reveal the pivot joint or exclude it. I want to see the circular brake assy, so as to trace and draw it.

I have layers with some clipping planes on, so as to turn the plane on and off.

Hi Steve -

I tend to draw it in a perspective viewport so that I can clearly see where I’m snapping.

That’s fine, just draw it in the “Left” viewport.

Assuming you are not snapping to anything when you create that clipping plane, it will land on the active CPlane in that viewport. From your image, it’s impossible to tell if there is a custom CPlane active there.

Just draw it in the “Left” viewport and the, in the “Top” or “Front” viewport move it until you see what you need in that “Left” viewport.

Hi, here is what happens.


then

then drag it though it already is hiding the arm, but in the wrong view.

it wont drag willingly, absolute sod, like a dog gone flotbott !

and still the arm is visible in left view.

Hi Steve -

Your first image is one step too late…

If the “Top” view is active when you start the ClippingPlane command, that’s the view that will be clipped. I suggest that you maximize the “Left” viewport before running the command to avoid that happening.

But you can also simply select the clipping plane and change which view it clips from the Properties panel.

Hi, aha, left active, then draw rectangle on left view, and its hidden the arms but also the brake assy,
so select move tool and in top view move it left, but its absolutely impossible to slide it left, why is it so darn difficult to move ?

try nudge tools, nothing happening.

rhino dislikes meshes. very badly so.

zoom in to top view and hit nudge, also try ctrl nudge, things are moving 0.1inch every 10 secs.

then nothing is happening 5 mins waiting then rotating circle appears another 1 minute or so, than phew I AM BACK IN.
this is scary, meshes a nightmare. and all my work involves them now.

It takes about 4 seconds for the viewport to become responsive again after having completed moving the clipping plane.

Hi
you click in left pane and move and its like on ice, mine refuses, its jerky at best, all I can do is nudge it a bit at a time. It simply wont drag as such.

Hi Steve -
Could you zip up the following folder on your machine and post that here?

%appdata%\McNeel\Rhinoceros\8.0\settings

-wim

Hi,
I dont have that address !

C drive has
C:\Users\Steve\AppData\Local\McNeel\Rhinoceros\8.0
but no settings there.

AbeMeda path contains McNeel and Appdata and Settings
finds nothing on any drive inc C

Hi Steve -

You need to copy that string into the address field in Windows Explorer, not try to go look for it.
At any rate, since your 3dm file with all geometry is slow on any machine, and the issue is filed and on Steve Baer’s list, we won’t be needing that information at this time.
