Hi

I have the following problem, when I start modeling i.e. create a polycube and start extruding in a variety of situations (if I combine 2 rotations) the loca coords of the extrude tool will "mis-align" Z follows the normal of the plane but X and Y sit on the surface but are not aligned anymore with the edges of the face... is there a way to align the transform tools to the face you are currently working with?

I am attaching an image, cube after some extrusions, local X Y axis od the tool are not parallel to the edges of the face.

any help is greatly appreciated

Im not really sure if this will work, but try deleting the history and freezing the transformations on the object. Or you can use the regular component editing tools to reset your problem. The tool you see on the pic works off the normal of the poly, and you have been twisting and extruding the same normal for a few steps now. That is why it's twisted. Let me know if my suggestion works for you.

uhm... not working... I cannot believe it never happened to anyone else...

try it yourself:

1. create a cube
2. rotate on the Y axis
3. select a side face
4. extrude, rotate it around Z axis, move out
5. local axis gone wild!

I believe it calculates the local axis in relation to the original local axis when the cube is created, with every transform it "averages" a new local manipulator... OR when I make an extrusion with a rotation the normals of the faces around the selected face are not anymore at a 90 degree angle to the face they belong...

I noticed another thing: as soon as you make a rotation during an extrusion the X Y axis "flip"...

GOD! Why are you mocking me!!!

Ahhhrg!

anyway thanks for trying.

Onre other thing I forgot to mention, if you click on that little light blue double circle thing that comes off the tool , changes it to a world manip. mode. Try that and see if that is what you want.

yes I know, the world coords handles always point along the world grid axis, the local axis are calculated in relation to the shape/polygon normals... in a cube it follows the normals of the side faces + the face it lies on, but if you extrude to a polygon with 2 segments if the new faces are planar with the original ones the local axis will be ok but if you select and rotate only 1 segment the new local axis of the extruded cube will be an average of the 2 sets of normals... no wait! sometimes it works sometimes ti doesn't....

AAAARGHHH!

what I was looking for is a way to align the local handles fo a manipulator to the currently selected face, instead maya thinks world and local (as local to the object) but not local to the component...

it's not a big deal I just have to use a combination of move and rotate instead of extrusions and I have to complete the whole model before posing it (I use to model in a "sculptural" way I pose and rotate the limbs\joints while modeling...) but the thing is that I cannot believe that something that simple has never been implemented!

thanks anyway

have you tried the move component tool?

Hi

I'm sorry Lyr but could you be more specific?

edit polygons > move component. if it gives you a wrong component type error re-select the thing you want to move press 'g' and it should work.

hey. polyMovecomponent would be exactly the same, its what extrude uses. guess you gotta ask the question about how you'd arange the local axes XY for an irregular face? nice regular cube faces aligned on world axes is a pretty special case. as is, id guess it just takes a path/rotate of least resistance from world to the normal of the average plane of the face's vrts (it just turns to face normal). maybe it'd be nice if the local XY were spun about Z, taking into consideration symmetry it might find in the face, perhaps other apps do this? not sure how trivial this task would be.
