Hello,
Attached is a Bezier patch creator, adding a new item to the Draw menu. It has some fixes and improvements over the first release, which I had posted a while back at the forums at sketchup.com, but those seem to be down now. The main changes are:
o Patch would sometimes not appear where you first drew it. This is fixed.
o A Bezier parameters dialog appears when you first select the tool.
o Removed the Bezier Grid menu item (an edge-only version of the patch), though this may be restored if you wish by uncommenting a line in the bez-patch.rb file.
To use:
After unzipping the zip or tar file, a bez-patch-1.1/ directory is created. Move the two folders inside it into your plugins directory. In Sketchup, type at the Ruby console
load 'bez-patch/bez-patch.rb'
and you'll be ready to go. (If you always want it available on startup, move the file bez-patch/bez-patch.rb up one folder so that it is in the base plugins/ directory.) After selecting Draw > Bezier Patch, a parameters dialog appears with: U Order, V Order, U Steps, V Steps. U & V refer to the 2D patch axes; Order refers to the number of control points in each direction; and Steps are the number of faces created in each direction. After clicking OK, click once to place a corner, move and click again to place another corner, then move and click again to pull the second dimension. Right-click on patch to edit the control points. Individual points and lines between points may be dragged. Using the arrow keys while highlighting a control point will lock the axis of movement along one of the major axes. If you later wish to change the number of steps in each direction, use the VCB while in edit mode; order is not changeable after creation.
It does not use any SU6-specific features, so should be fine in SU5.
Cheers,
Victor
