Spin one and other hair pulling lessons


Spinning too several readings of the Blender docs to understand my mistake...

History is made -- my first spun object. Blender managed to make what is the simplest modelling tool on the shelf into something uniquely hard to use --- to be fair only because like with many Blender operations it makes sure that it doesn't work quite like other packages.

1. Start with a shape (open along the spin axis)
Online tutorials suggest that you create a spline by deleting the vertices of a cube and the hijacking the cubes entity properties -- a bit of a clanger piece of functionality from the start --- maybe there is a way of laying down raw vertices but I can't find it.

2. The spin will take place from the 3D View in which you invoke the spin operation --- which is what was causing my hair pulling. I'd not extended the toolbar within the right view so I was trying to spin along the wrong axis.

3. Get the 3D cursor right onto the edge of the line by using the snap cursor to selection (Shift+S -> Cursor to Selection).

4. Spin! Then modify the spin parameters such as the number of steps and degree of spin.


Phew! Earlier this morning I discovered how to present an unshaded texture map (a background image) on a plane using the Cycles renderer. It took an 8-minute video tutorial and the rather involved use of a several nodes. Ouch! For such a simple requirement that's a rather grueling procedure.

Time is running out. I'll be back to work in a few days and Blender won't be getting much of a look in until a hefty amount of technical writing is completed.

The scene outside the window looks like it's being pumped through a filter. At least it's not shaded!

It never rains but it ....snow forecast

 We're heading towards Winter's end, but we might not have seen the last of the ice and snow. In the world of Blender, I got a sudde...
