Explizit modeling with absolute and relative coordinates in Rhino 6 using the examples of staircases (20 min)

Start Project: setup units (cm) and tolerance (0.01)

Create curve with CMD “rectangle”: Draw first horizontal and vertical steps

Enter “relative coordinate” (@20, 100) instead of absolute coordinate (20, 100) for third step

Convert curves to surfaces with CMD “Patch” (Surface spans: 2)

Create “Surface” (from 3 or 4 corner points) immediately: absolute and relative coordinate options as a komplex way of drwaing surfaces

Create “rectangular plane” (3 points): use ortho mode for snap and only enter width and width direction (finish with mouseklick)

Create “rectangular plane” (corner to corner): use relative mode and horizontal or vertical rectangle

!This chapter is only a repetition of the previously shown workflow! “Join” (not patch!) all surfaces to create one object!
