Using the Photo Point tool, proceed to model the dormer's bargeboards and roof surfaces.
- [Instructor] Our next task is to model the dormer roof here. So let's go to the Window menu and open up Match Photo. And then click on the photo point tool. Zoom in here. And click the peak of the dormer roof. Then go to photo two. Zoom in here. And use the photo point tool again. And click right there on the guideline. Then orbit.
And we need to draw a line at the intersection of these two guidelines. So type L for line. And draw in the line. It's always a good idea to orbit and see if that line is in the correct position. And I'd say that looks pretty close. So let's go ahead and delete the guidelines. Then draw in a line in the green direction some arbitrary distance. I can now erase this vertical line.
Go into photo one. Select the line. Rotate it. Press the right arrow to indicate the red direction. Click the axis point. Click the end of the line. And start rotating. Then type in, let's try six and 12. Apparently that's not enough, so let's try eight and 12. So 8:12 enter. That looks like it matches the slope angle exactly.
So I'll zoom in here. Go to the move tool by pressing M. Click the end of the line to start moving it. Press and release the option key on the Mac or the control key in Windows. And let's move this down, say 11 inches. So type 11 enter. And then press L for line. Draw in a vertical line. And another vertical line here.
And let's select these edges and erase them. I'll orbit. Press P. Let's push that back an inch and a half. So type 1.5 enter. Space bar. Triple click on the object. Press G to make a group. Now I'd like to copy that and mirror it around to the other side. So I'll press M for move. I'll start moving it in the green direction. Press the option key on the Mac, or the control key in Windows, to make a copy.
Press S for scale. Zoom in here so you can identify the middle grip. Click that grip, and then type -1 enter. Then press M for move and move this back over. Let's take a look in photo one. Looks good. How does it look in photo two? Also looks good as far as we can see. We now need a roof surface that goes on top here.
And at this stage it's impossible to know how far back it goes but we'll just extend it back some arbitrary distance. So I'll zoom in here. Double click on this element. Select the top surface. Copy it to the clipboard. Click outside the group to close it. Press V or choose Edit, Paste in Place. And then press S for scale and scale the surface back some distance. I'll press G to make that a group for now. And I'll neglect extruding that surface until later.
I'll hold off on that because I'm anticipating needing to trim this surface where it intersects with the major roof on the side of the house. Now over here I'm going to repeat the procedure. I'll double click on this large board to open it. Click on the top surface. Edit, Copy. Click outside to close. Edit, Paste in Place. Press S for scale and scale this over. I'll scale it to match the other side.
And I'll press G to make a group. Let's take a look in photo one, and photo two.
