CPlanes Rhino 8 not working?

Hello, I relocated my cplane as I was used to in Rh7, the position is changed but my viewports don’t change with it, as it did in Rh7.

I played around with Cplane/world button in the lower left corner, and also with the auto C-plane button in the lower mid, but it has no effect.

do I miss something?

Albert.

Hi Albert -

That part of your comment leads me to believe that, in Rhino 7, you had Rhino Options -> Modeling Aids -> Construction planes set to “Universal construction planes”. The default is “Standard construction planes”.
If that’s not the issue, we’ll need more information from you.

that’s the one! thanks a lot!

Another one, when measuring (distance) it keeps measuring relative to WCS, but I want to measure relative to my CPlane. is there also a setting for somewhere?

Hello - I am not sure what you mean - distance itself is not relative really - but the full report shows deltas for both:

Command: Distance
First point for distance ( Units=Model_Units )
Second point for distance ( Units=Model_Units  Undo )
CPlane angles and deltas:	xy = 9.377  elevation = 0.000  	dx = 25.469  dy = 4.206  dz = 0.000
World angles and deltas: 	xy = 0.000  elevation = 9.377  	dx = 25.469  dy = 0.000  dz = 4.206
Distance = 25.814 millimeters

in the picture below, the box (500x500x500) is on WCS and on Cplane which is also on WCS.)

see the distances.

in the picture below I changed the Cplane and then I want to measure the distances relative to Cplane (delta X/Y/Z)
but those remain the same as in the first picture. ( I also toggled between CPLANE and WORLD)

the dimensions should be something like this (I rotated the box which I don’t want to)

I hope I made clear what I mean.

best regards, Albert

Hi Albert - please look at the whole report - above the world deltas are the CPlane ones.

Hi Pascal,

I solved the problem I think,

First point for distance ( Units=Model_Units )
Second point for distance ( Units=Model_Units Undo )
CPlane angles and deltas: xy = 44.567 elevation = 0.766 dx = 616.932 dy = 607.669 dz = 11.571
World angles and deltas: xy = 45.000 elevation = 35.264 dx = 500.000 dy = 500.000 dz = 500.000
Distance = 866.025 millimeters

I was under the impression that this was different in Rh 7 which isn’t I just find out.

I am relatively new with using cplanes, need to practice a bit more.

I still don’t understand the world/Cplane function in the lower left corner; I see no differences, and auto Cplane is also still abracadabra,

why is the lock gray? is it not functioning, and why?
