How do I crop or stretch materails I have on the screen?
When you drop brick onto the screen, the WHITE sizing squares let you put more brick into your project in your same scale. Brick, windows and doors are already correctly sized for your scale automatically when you drop them onto the screen.
There are some times when you might want to make materials bigger/smaller or you might want to paint more windows into your project.
If you want to make a brick bigger, click the right button under the "drawing mode label" (it is a picture of a window getting bigger) If you click the symbol you will see black sizing squares around your brick. Drag a BLACK sizing square and your brick will get bigger.
If you want to crop or paint a window or door, click your object and then click the paintbrush scissors symbol. Your object will have white squares around it and you can crop or paint the object.
