Hi Tom,

re:

Sorry no there isn't any way set up to make the 3D view rotate only around the yaxis. But it is possible to modify the script to change which plane it makes stuff on.

To change it, open the script in a text editor and you'll need to edit 3 lines, the first one is line number 12 which has this:

mirror_factory.setInput( 1, moi.vectorMath.createTopFrame() ); // First point and plane for mirror line.

Edit that to use createFrontFrame() instead. Then line number 13 has this:

mirror_factory.setInput( 2, moi.vectorMath.createPoint(0,1,0) ); // Second point of mirror line.

Change that to say moi.vectorMath.createPoint(0,0,1) so the mirror line will be going up in the world z direction. Then the last place to edit is line number 34 which has this:
factory.setInput( 1, moi.vectorMath.createTopFrame() );

Set that to say createFrontFrame() as well. After those modifications, the script should generate the pattern in the Front view instead of the Top view.

Sorry no there isn't any way to do that for mouse rotation. But it is possible to set up the arrow keys so they will do rotations, see here: http://moi3d.com/forum/index.php?webtag=MOI&msg=6145.2

Very cool, Michael and thank you.

Sorry for repeating myself but your software is really a pleasure to work with -
and the more I dig into MOi to more I admire the simplistic and yet very ingenious
approach behind it.

Thanks Tom, I'm glad that you are liking MoI!

This kind of locked rotation is very useful to judge the design of an object from all sides
while refining its shape incrementally. Make a little change- rotate and judge, another
change.-rotate, etc. Like a model on the end of a catwalk ;-)

But : The rotation is is not smooth as it works with steps of 3° and it rotates pretty fast.

Is there any way of making the rotation smooth and slow ? Thx TOM

Hi Tom,

> Is there any way of making the rotation smooth and slow ?

For the arrow key movement as described here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=6145.2

You can change that to be slower by editing the script, where it has the value of 3.0 in the script change it to a smaller value like 1.0 or 0.5 or whatever works best for you and that will make the arrow keys rotate in smaller increments.

0,25 is an awesome speed ;-) one more step towards the ultimate
MOI workflow - grazie !
