Moving Block Nodes In View Plane
 
When using the move node tool for blocking, is there a way to restrict the movement so that the nodes will only move in the view plane? (i.e. the nodes would not be able to move into or out of the screen)

Thanks,
Timothy

yes it's there, go to "move vertices"---Movement constraints---------Fix the direction that you don't want to move.
eg: if you want to move only in the Z direction then fix X and Y.

If you want to align it with respect to a reference vertex then go to the second option in move vertices "set location"-----select reference vertex-----select modify direction-----select vertices to set then apply.
eg: If you modify only in Z direction click the z direction only.

Further Explaination
 
Thanks for the reply. The problem is that I am meshing on an orgainc geometry that does not line up with any of the primary directions (x, y, or z). I would like to be able to constrain the motion in an arbitrary direction based on how I am currently viewing the geometry.

For example if I were viewing the geometry from the standard isometric view I would only want the points to move in planes that were parellel to a plane that passed through the points (0,0,1), (0,1,0), and (1,0,0) i.e. I would not want the points to move in the direction <1,1,1>. Also, if I were viewing the geometry from the x-axis I would only want the points to move in planes parellel to a plane passing through the points (0,0,0), (0,1,0), and (0,0,1) i.e. I would not want the points to move in the direction <1,0,0>. Like I said though, I would like to be able to do this for an arbitrary view point so I would almost never need to restrict the movement in a way as simple as these examples.

I hope that clairfied what I was asking instead of making it more confusing.

Best Regards,
Timothy

You could create a local coordinate system...

I will think about it, I vaguely recall that there was a way... Funny since this is the only way to move nodes/verts in most meshing tools.

Sounds Good
 
Thanks Simon

So far I have ended up with so many block edges going in so many directions that I have been using the fix direction option and choosing an edge that looks about the way I want to move a point.

If you figure it out let me know because that would be very useful for me.

Best Regards,
Timothy

I need this feature too.

Using coord systems is not the way.
