how to tilt and stretch multiple objects in 3D space in tandem?

[jetted4]

I have a drawing made in a single plane and I want to drag one corner up a pole (polyline) so that the entire drawing stretches and all of the features of it still remain in a single plane.  It is a simple drawing, so if needed I could just drag each individual point and figure out its new location, but this is just an example.  I would like to have a way to stretch and tilt more complex drawings than this one.

I attached a DWG file with an example.  The cyan drawing is my original flat 2D plane figure. 

The yellow drawing shows the left corner having been dragged up the red "pole", but the other portions of the figure are still in the original plane and haven't been changed so now my drawings is buckled.  But I want all of the lines of the drawing to be dragged along in tandem so that the end result is still a flat drawing in a 2D plane but elongated and tilted in 3D space due to my stretching the one corner up the red pole.

I am fairly new to using 3D modeling and am not figuring out a way to do this.  Any ideas?

Hi @jetted4,

Thanks for sharing your drawing, that helped understand much better.

In general for vector based programs like AutoCAD, to tilt and stretch linework, only one grip can be selected, the unselected grip acts as the fixed base point. When both grips are selected, the entire line is moved equally to the new elevation, which seems to be what is happening with this shape. 

For this complex of a shape, each grip or cluster of grips point would need to be moved independently to tilt AND stretch. 

All the best,

You can scale blocks in one, two, or three dimensions independently. Arcs and circles can only be scaled uniformly.

Create a block of the triangles and then determine the scale factor for the scaling.  FOr the following it was 1.03358522 in Y.

That looks like does exactly what I needed.  Thanks  🙂
