Re: [Inkscape-devel] remove/apply transformations?
---8<---Snip--->8---
Lets say I want to draw a regular hexagon. I will draw 3 identical lines, rotate one 60, another -60, then apply the transformations. The endpoints of these paths will give me the control points to draw the hexagon.
From this example, however, I don't see why you need preserving transformations - if you apply them at once! This means you just want the rotate command (in the Transformation dialog, I suppose) to work in the "optimize" mode, i.e. apply the transformations for you. Or am I missing something?
In this particular case, optimize mode would work well, but I am actually constantly switching between the two.
Suppose I'm drawing a snowflake: http://members.rogers.com/rcrosbie/images/woodworking/snowflake_2c.jpg
I only need to work on one branch of that snowflake, group the paths and the others are copies of that branch that are rotated. In this case I want to work in preserve mode because If I make a change to one of the branches, I can copy that change to the transformed groups. But suppose I want the side-branches to meet. I will then use my hexagon example above to find the point where side-branches intersect and use that as my endpoint.
I usually want to optimize the transformations in jig objects that are used to find points for my preserved object. Does that make sense?
I wouldn't have to do things like this if inkscape had some CAD-like path features such as: Connect path A to the midpoint of Path B; Clip path A at it's intersection with path B; etc. I'm constantly making objects to precisely find these points that I need.
Check out this celtic knot: http://members.rogers.com/rcrosbie/images/woodworking/plate5of3a.jpg
It consists of 5 copies of the same path that are rotated, but I had to draw a lot of intermediary objects and paths to ensure that that one path would be seamless when it was rotated and combined into the larger object. It's the intermediary objects that I need to apply the transformations to.
Cheers, Rob.

I think the more-precise cad-like path editing ability would be a great feature. You should push this on the inkscape RFE (sf.net/projects/inkscape)
