Originally I had this model (note 90° degrees in the upper left corner).

Then I wanted to make the whole model looking more narrow, so I deformed the model. I replaced the buildings on right side for original ones and adjusted their position and angle. Now I have this problem with the upper building, because their angles are too odd. So I would want to deform them, but - how?

This is original plan

and this is what I have after deformation in actual point.

For example, these walls need to be straight:

What would you do to correct them?

Mitcorb is right, I have to delete the triangles and create some inner edges.

Thanks. It works. Just it take me a lot of effort to zoom exactly to the joint.

I actually dont know what is internal edge and ind if it has. You think it has not?

I see the wall is deformed. Probably I should to deform the "North" part of the wall because it is very thick.

I should change the view to select the edges and deform them. What view to select? Coz I don't see inside the wall.

I try to rotate the blue line

into the point in red circle.
But I am helpless. I don't know where to click. I know I should click first on the bottom point of the line.

1. There is black circle with green dot placed horizontally
2. There is blue circle with green dot placed horizontally
3. There is black circle with green dot placed on left roof surface - skewed
4. There is black circle with green dot placed on right roof surface - skewed
   Which one I should click?

Also should I lock it with shift before I drag towards the red circle?

Then should I click on

1. purple/violet dot
2. green dot (it is placed on streight line going out of the blue line)
3. black dot
4. red

I'm quite not sure.

Ps: I change object imported from gallery, originally obviously purposed for Google Earth.

Is it possible to join two lines? For example, I have a wall with a texture in which are "door". Not door really, just empty area. Now I would like to take top line of the "door" and to move it down to bottom area, so whole area looks like rectangle. But it is not because the bottom line is separated into two lines. So can I make one line from that who lines?

It as late night when I had the problem. I saved the project and closed PC. When I started today, so all was right. Except, that when I loaded the file, it looked the same as on the screenshot. But when I moved and zoomed so everything in right in parallel view. I will come back here if I will have some similar issues. Thanks

That was Perspective. After correction to Parallel Projection was OK. But Now I don't see roof in Parallel View, no fog.

I use googlescratchup version 8.

I have this

and want to close look on the wall, but when I get closer, I see nothing or everything disappears. How can I watch the wall closer?
