OFFSET EDGE - Pet Pallet

[Anonymous]

Is this a wish or a bug?

Working with polygon shapes and the Offset edge tool on the pet pallet works fine, it does just what you want.

However, when it comes to editing a polyline or a selection of unclosed elements (see topic on this), such as a selection of walls or lines, then the behaviour can be rather strange.

Select several joined lines/walls and then edit the end one using the Offset edge.

Then what happens is this:

Rather than extending the adjacent elements and keeping the end one at the original length, you find it lengthens or shortens the element, depending on the undrawn line between the first and last element you have selected.

In the example below, the closed shape would be a triangle, and the wall is either lengthened or shortened according to which way you offset.

This is not what I want to happen.

Am I the only one who thinks this is not what the edit should do?

While we're on the subject I have another complaint about Offset Edge. Once started the cursor does not recognize other edges (no half-filled pencil) or invoke guide lines. Only vertices are detected. As other pet palette functions do not suffer this malady I consider it a bug.

geoff - are you sure about that?! i get both perpendicular indication when hitting another parallel element, and linear element indication if hitting any other edge . . .

Right you are Ben old boy. The problem comes when you move your cursor away from the stretch line, like in the common case of aligning one edge with another. This is what the screen shot shows. Sorry but the cursor is not captured, but is attempting to align with edge of the upper rectangle. No go. Sure I can hit the corner vertex, but in lots of cases those nodes might be crowded or off screen. I just checked and the same thing happens when shift-constraining a vertex stretch and moving the cursor to away from the constrained vector. Vertices yes, edges no. But in that case it's easy to trigger a guide line or two first since you can move the cursor all about. With Offset Edge no guide lines.

gotcha. bug. no question(!)

(your earlier screenshot looked as though you were attempting something similar to mine...)

cheers!

I see my originally reported offset polyline bug is still not fixed in ArchiCAD 11
unless of course it really is a (somewhat useless) feature

Try offsetting from a corner node.
