and... for those totaly new to Wings3D... upon downloading and installing it on your machine... open it up, go up into the top menu...
Edit> Preferences... and then look for the Highlighting section and make sure to check active "smart Highlighting" ... this feature will allow you to mouse over verts/edges and or faces and see each lightup for possible selection...
Now then, for those who have never tried Wings3d before... after making sure that this feature has been checked off.... to pop a primitve on screen to work with you have to have your mouse cursor in the work area/canvas... right click and you should see a list of primitives....
choose "cube" ....and then when you see the cube on screen hit "r"... this automaticaly sets the axis of the object to wings default perspective ... it is important to do this each time you pop a primitive on screen, because some times via bug in app the primitive comes in off axis... and ...
Axis is everything... when creat'n anything in 3D....
So
right click and pop a cube on screen....
then hit the
middle mouse wheel/button move your hand from side to side and go for a
camera ride

... sweet eh.... this dolly cam is also your buddy....
now
roll that mouse wheel and zoom in and out... cool

now hit "r" and you back at the starting axis position....
now hit
shift/tab and see the sub-d preview look at things... note... this sub-d takes a lot of power resources when working with larger file sizes... so...
lets go up to the
shaded white pyramid icon up top left, and hit it... now you are working with a boxy cage sub-d view.... still pretty cool, but for the most part folks, I rarely work in sub-d, but rather mainly use the shift/tab to preview what my model will look like smoothed (subdivided )... and for work, it is the chunky non sub-d method which I find works the best...
Extrude and Extrude>region along norm from z axis ...... take a cube and left click onto and select opposite end faces... when they are selected they should be red in color.... now with both opposite ends selected, right click and hit "Extrude>normal " and extrude out say a cube's size... like this... and here is the pic also showing the axis... this is the start to our HAPVehicle here... and now when ever I am moving or extruding something out I know which way everything is going because I always work my models with the axis setting and rules in mind... Z= front to back, X= side to side and y is of course always top to bottom...
