Offset-function per ruby (simple)

artmusicstudio

hi,
is there an equivalent for the skp-function "offset" in ruby for simple forms like square or circle ?
thanx stan

If you group the objects it makes things much simplier:

g.move! [1,1,0]

Moves the group by the vector array argument. (The API dictionary says the arg should be a Geom::Transformation instance, but the method also takes an array representing a vector.) Does NOT add the move to the Undo stack.

g.transform! [1,1,0]

Moves the group by the vector array argument. (The API dictionary says the arg should be a Geom::Transformation instance, but the method also takes an array representing a vector.) ADDS the move to the Undo stack as "Move".

I would assume that these methods may also accept a Geom::Vector3d argument ?

For simple objects you can move them without grouping.

Assume c is the reference to a circle object.

c.parent.entities.transform_entities( [1,1,0], c )

Or for an array [e1,e2,e3,e4] of edges making up a square:

e1.parent.entities.transform_entities( [1,1,0], [e1,e2,e3,e4] )

The above methods add to the undo stack.

Also be aware strange results may happen if the entities to be moved are not in the current editing context.

Were you looking to move objects, per Dan's replies, or for a Ruby equivalent to the offset tool (i.e. to create a "parallel" shape inside or outside the original)?

hi, slbaumgartner,
yes , you got it,
what i look for here (though dan's advice is also helpful for other things)
is in deed the offset-function, creating a parallel shape (only simple forms like rectangles or circles).

you can try this:

simply works for faces(polygons) and polylines
