Moving a Line or Edge

[medeek]

I am trying to move an edge of a solid after I have push pulled it into shape and added an extra line, however the Transform! method does not seem to work:

                    h_pt1 = [xvalue, @Hx1, @Hy1]
			h_pt2 = [xvalue, @Hx2, @Hy2]
			h_pt3 = [xvalue, @Hx3, @Hy3]
			h_pt4 = [xvalue, @Hx4, @Hy4]
			h_pt5 = [xvalue, @Hx5, @Hy5]
			h_pt6 = [xvalue, @Hx6, @Hy6]
			h_pt7 = [xvalue, @Hx7, @Hy7]


			group3 = @truss_component2.entities.add_group
			entities3 = group3.entities
			group3.description = "Hip Rafter"
			group3.name = "Hip Rafter"

			new_face3 = entities3.add_face h_pt1, h_pt2, h_pt3, h_pt4, h_pt5, h_pt6, h_pt7
			new_face3.pushpull plydepth
		
			midline = xvalue + @Ply*0.5

			lp1 = [midline, @Hx5, @Hy5]
			lp2 = [midline, @Hx6, @Hy6]

			linebottom = entities3.add_line lp1, lp2

			# Translates to vertex of fascia
			lb_trans = Geom::Transformation.new([0, -@Plyhalf, 0])
 			linebottom.transform! lb_trans

An Edge is an entity and can not be transformed by .transform! use .transform_entities instead.

mod = Sketchup.active_model
ent = mod.active_entities
sel = mod.selection
vue = mod.active_view
h_pt1 = [xvalue, @Hx1, @Hy1]
h_pt2 = [xvalue, @Hx2, @Hy2]
h_pt3 = [xvalue, @Hx3, @Hy3]
h_pt4 = [xvalue, @Hx4, @Hy4]
h_pt5 = [xvalue, @Hx5, @Hy5]
h_pt6 = [xvalue, @Hx6, @Hy6]
h_pt7 = [xvalue, @Hx7, @Hy7]


group3 = @truss_component2.entities.add_group
entities3 = group3.entities
group3.description = "Hip Rafter"
group3.name = "Hip Rafter"

new_face3 = entities3.add_face h_pt1, h_pt2, h_pt3, h_pt4, h_pt5, h_pt6, h_pt7
new_face3.pushpull plydepth

midline = xvalue + @Ply*0.5

lp1 = [midline, @Hx5, @Hy5]
lp2 = [midline, @Hx6, @Hy6]

linebottom = entities3.add_line lp1, lp2

# Translates to vertex of fascia
lb_trans = Geom;;Transformation.new([0, -@Plyhalf, 0])
#linebottom.transform! lb_trans
entities3.transform_entities(lb_trans,linebottom)

As Sam says, transformations only apply to containers like component-instances, groups and images.
A Point3d does not have a transformation, BUT you can use point.transform!(transformation) it relocate it.

Basic entity objects - like vertices, edges and faces - have to be transformed using:
objects_parent_entities.transform_entities(a_transformation, [array_of_objects])
this works with any kind of transformation; or for a vector based 'translation':
objects_parent_entities.transform_by_vectors([array_of_objects], [array_of_vectors])
note that each object in the first array must have a matching vector in the second array...
Also if you are using the these to move say vertices, don't also include some edges or faces which use those vertices - otherwise the vector transformation will be done twice, with unexpected consequences...
