First, we import our stair CAD or other floor plans into Sketchup, so that we have a rough template for making stairs. Then, in the toolbar on the left side of Sketchup, we found the rectangle tool, chose the rectangle tool, and stroked the stairs in our drawing. Stairs are usually rectangular, so it is easy to draw with the rectangular tool. After using the rectangular tool to frame the stairs, we will see that the steps of the stairs turn white, and we will use the rectangular tool to frame all the stairs. Because the stairs are almost the same steps, we can draw them first and then do the stairs, and choose the push-pull tool on the left toolbar. Put the push-pull tool on the first step of the stairs, pull out the model, Enter the height of our steps, and then press Enter to raise the stairs to a suitable height. After that, we will pull the stairs out in turn, and the height will be balanced, thus gradually forming a complete staircase, but we must calculate the height of each stair step. After completing all the stair steps, we have completed a very simple stair diagram. If we want more details, we can modify them ourselves.

1。 First, import a cad model and draw a rectangle on the stairs. R (rectangular command) 2. P (Push-Pull) Pull the rectangle up one step. Usually between 150-200. 3。 Select an edge, and m (move) copies an edge to the upper left corner. (according to the actual situation. )4。 Immediately after copying, use the keyboard to enter the number of remaining steps. For example, enter * 10 for ten steps.

There are generally two ways to build Su spiral stairs. One is hand-painted and the other is plug-in.
