You select the heptagrammic face, hit: scale->stretch (non-uniform scale)..., enter the desired value (scale by or set value to ...) and "perpendicular to selected face".

If you want to colour each spike of a shape like the great stellated dodecahedron individually you can open it in the base stellation view, put it into a memory, retrieve it again, activate the base polyhedron view and give each triangular face the colour you want by hitting Ctrl+c.

I'd call it a rhombic 180-hedron and I guess you'll have to do the colouring by hand using Ctrl+c.

When this model is opened in the library it is displayed in the base stellation view. So you can fix that colour problem easily by putting the model into a memory, retrieving it again and activating the base view. Then you can select the inner parts and give them a different colour by using shift c....

If you have stella fold and unfold the net in the 'folding net view' you see that the net is complete.

Great!!

If you allow a pentagon and a triangle to share the same colour at one vertex, you get along with four colours:



Ulrich

much easier indeed, cool!

I tried it in the following way: Take the compound of 5 tetrahedra and put it into memory 1. Then take Millers Monster, select a pentagram (they all should be red in the auto colour option), you hit c and you slightly shift the red colour a bit lighter or darker to avoid colour conflicts in the foll...

Pretty magic and cryptic I know! Ideally someday I should make the add-from-memory a bit more clever about orientations!

And doing that, could you please take care of the "put models on faces"-tool too?

Ulrich

But... my problem seems to be the position of the added Rh. Pr. in the cube- as you mentioned already. I work on 2 pc's and both show the Rh.Pr. rotated somehow in the cube. See picture. https://www.dropbox.com/s/0rxfbj63cn1jjro/Screenshot%202015-03-02%2018.05.17.png?dl=0 Too bad for me. Now the ga...

Seems that I was a little too hasty describing the procedure. In the rh prism, there are 8 edges where squares and rhombs meet at 90° and 4 edges where only squares meet. At two of the latter ones, the squares are forming an acute angle (=> "acute edges"), at the other ones the angle is shallow (=>"...

Jos, it can be constructed quickly in the following way: You choose the triangular prism (hit 3,4,4 and ok in the search field). You put this into memory 1. Then you select a square face and augment it by the model in the memory 1 (selected face only, and right (->), to get the orientation ok). You ...

... Doing it your way also means that you could facet using the original vertices of the trapezoidal hexacontahedron to keep the original face shapes around the bottom. Rob. Unfortunately that doesn't work because the four vertices you need are not lying in a plane. I had to take the stellation ver...

Perhaps a new occasion to think about enhancing that "put models
on faces/vertices-tool"?
