positioning vertex on plane

[Anonymous]

I want to move one vertex to the position exactly on  plane defined by rest of vertex of polygon.

I know it is easy if the plane is same to XY or YZ or ZX (just scaling 0 for all vertex) but how can i do that on arbitrary plane?

Are there any easy ways for that?

example:

Hi!

You can't do this on one step, but you can create your own reference plane and make it live:

1. Triangulate your face

2. Duplicate and scale up the triangle defining the correct reference plane

3. Make the new reference plane "live".

4. Move your vertex on "live" reference triangle plane.

Thanks mspeer

I tried your method but...

maya placed surely on reference polygon but not on axis where i need.

honesty say, I can achieve it with 10 or 20 step,but if there are handred of faces for modify, i want to retire modeling.....

Hi!

"...maya placed surely on reference polygon but not on axis where i need..."

Sure, it's a snap function, it does not work as movement limit, blocker.

I don't know why you want to move the vertex in World Y - Axis only, or why you need to do this for multiple polygons.

There is no tool to do this in Maya, You may combine several tools to achieve what you want, but the best way would be scripting.

It should not be too hard to calculate the point on surface (your reference plane) based on your preferred movement direction and move the vertex to this location.

hm.. OK, I will think about scripting.

Anyway, thanks mspeer
