how to rotate (spin) a mes to the left (long story)


(MrE) #1

Being new to blender < two weeks) i scavenged the net for tutorials to help me on my way.
A lot of tutorials i have seen seem to leave out some steps in the process. Most of the times i can figure it out by my self, but not this time.

At the moment i am working on this tutorial http://members.yourlink.net/gruff/mesh/ the problem i have is that when i want to spin the exterior of the rotor (step 6) it only spins to the left and makes a big loop. ( i clicked the clockwise button to try if yhay changed the direction of the spin, but to no avail)

When i moved the mesh for the exterior to the right and spin it and that worked, but it still formed an enormous loop (resizing only left me withe a deformd exterior).

When i moved on to the jet engine tutorial on the same page, i ran in trouble when trying to spin-dub the flaps. when i do that it spins around a very small center making a clustered cone of flaps.

My question is: is there something i am overseeing (did the maker of the tutorial leave something out that is ‘for granted’) or is it something that is wrong with blender (sometimes when i start blender up and i try to spin (step 6) it still rotates to the left but in the right proportion. when i then do a reload of my saved work and try it again the proportions are huge again)

did you want to know that the spin, spindup, and corkskrew commands rotate around the window’s z axis, and around the cursor?

the cursor location is set with LMB or shift+s and [curs->sel] or [curs->grid]

… and I don’t believe it was mentioned that scaling (and translating) can be confined to a single axis with the middle mouse button. Start the action in the direction of the axis you want to make changes in, then press the middle button.

PERFECT, although your message didn’t make sense to me at first, i now understand that the 3d cursor is the point that forms the center when i make a spin.

thanks a lot for your help.
