I am trying to design a snail in Rhino (this animal illustrates my learning speed of Rhino (-; ).
Record History is on.
I designed a spiral (Curve menu), added a small circle around curve at the beginning of the spiral and a bigger one at the end.
I then used a sweep 1 rail to build a first approach of the snail. I now want to adjust it to get the final result I wish.
If I adjust the circles diameters, I perfectly see the history effect: the surface is redrawn in accordance with the modifications. Fine.
But when I try modifying the spiral, I can’t find out how to modify its parameters (step, end of axis, …). I can of course move its points, but Rhino creates too much points in a spiral for this method to be handy.
Did I miss something or is history not allowing access to parameters modifications?
