Indicate wall line that roof is on:
Select the topmost horizontal wall at the position (1) in the picture below.
The prompt now reads:
Indicate first corner for width of building:
Select the End point snap at the top left corner as shown (2). The prompt now reads:
Indicate second corner for width of building:
This next point defines the other end of the gable, however it can't be picked directly as it is a point along the the left vertical wall which is in line with the external face of the front door wall. To pick this point we will use X Snap and Y Snap feature. Move the cursor over the End point at position (3), DON'T CLICK, hit the key and move the cursor toward position (4). You should see a dynamic dotted line drawn horizontally from position (3) to the cursor. Now simply move to the End point at position (4) and click. The prompt reads:
Indicate corner for length of building, or [T]ee to join existing roof:
We are now going to indicate the length of the roof. Pick the End point at position (5).
To make the selection of the correct points easier zoom into the area shown in the picture below the dialog box (the furniture has been switched off for clarity).
Re-select the Roof command and in the dialog box make sure that the 'Hipped' tab is selected and adjust the settings to match those below. Select 'OK' to continue.
The last section of the roof to draw is that over Bedroom 4 below (again the furniture has been switched off for clarity). Zoom into this area and once more select the Roof button again.
The process is the same as that we have followed on the previous roof section. Make sure the 'Hipped' tab is selected, there should be no need to adjust any other settings, before you select OK'.
Select the wall at position (1) and using the End point snap select two corner points (2) & (3). Again we must indicate the roof to tee into, so press the key and click on the existing roof line at position (4).
