1. Select Push/Pull.
2. Click on a modeling surface.
This modeling surface can be drawn by yourself with lines or rectangles, or it can be a surface on the existing modeling.
3. Select stretch direction or enter stretch length.
When you input the exact distance in the lower left corner, the positive number means stretching in the direction of the mouse; the negative number means stretching in the opposite direction of the mouse.
Q: Why can’t I push or pull some walls?
A: Only architectural surfaces can be modified in Construction. Structural surfaces cannot be modified.
Q: What are structural surfaces?
A: The walls, ceilings, and floors that are created automatically when you draw a floor plan. All surfaces that appear when you first enter Construction are structural surfaces.
Q: What are architectural surfaces？
A: The surfaces that you draw by using the Line (L), Rect (R), and Push/Pull tools.
The differences between an architectural surface and a structural surface are that you cannot push, pull, loft, move, or delete a structural surface. And you cannot set a structural surface as the loft path. However, these operations are supported for architectural surfaces.
Both architectural surfaces and structural surfaces support material paving and advanced material editing.
Note: You cannot modify floor plans or create holes for windows and doors in Construction.
