Is it way to draw always on CPlane with enabled snap? So all curves that you create with snap to objects will stay on CPlane and not on that objects?

Set one of the following scripts on a shortcut key - one enables snap projection just in ortho views, the other enables it in all views:


Project to cplane drawing aid - drawing aid mode which can be used to project all snap points onto the construction plane, by using the following scripts on a shortcut key:
script: /* Toggle projecting snaps to CPlane in ortho views */ moi.drawingAids.projectToCPlaneOrtho = !moi.drawingAids.projectToCPlaneOrtho;
script: /* Toggle projecting snaps to CPlane in ortho and 3D views */ moi.drawingAids.projectToCPlaneAll = !moi.drawingAids.projectToCPlaneAll;

Great! Many thanks!

Also wanted to ask, why if I set CPlane that is parallel to origins, and if I go for example to the top view it will go to the top of world but not the CPlane?

I'm not able to repeat that problem over here - I just tested setting a cplane parallel to the top view, and when I draw in it, the points go to the cplane as expected.

Can you show an example that is behaving differently?

Are you possibly being confused by the XYZ coordinate readout saying z = 0 ? That's because the coordinate readout is also in cplane coordinates as well, you will see a "c" prefix in front of them when that happens. Z = 0 in cplane coordinates is on the cplane.

That works for curves but not for Circle for example!
Does this normal ?

Edit : only for circle by Center on the middle of the face!

Hi Pilou,

It's working fine for Circle over here... But it's normal that it will only work for the first point pick in circle - the second point pick of circle is meant to track on a plane parallel to the cplane but moved to go through the center point.

Hi Michael, check this video:

Hi Andrei, thanks for the video, that helped me understand.

So there is some logic in the cplane mechanism where if the cplane has its horizontal and vertical axes aligned with any of the Top/Front/Right world planes, it keeps the ortho views in their regular world orientations.

I don't really remember why I set it up that way, probably I was worried about having the world Top view showing in the Front or Right viewport... But I agree it is probably better not to have that kind of exception in there, so I will modify it to work like you were expecting for MoI v4.

Thank you, that thing confuse me for a very long time.
Today I wanted to make script that will set CPlane and than automatically goes to the top, but I first thought of this thing and decide not to make it because in some situations like in video I do not want to go to the top.
