Rotating staircase making

1, set the system unit as mm.

2, create a stair column:

Draw a cylinder with a radius of 70mm and a height of 3650mm, and move the cylinder to the coordinate origin;

3, create steps:

Create a tubular body with a radius of 1 of 900 mm, a radius of 2 of 70 mm and a height of 50 mm; ; The number of sides is 4; Check Enable Slicing to start slicing at 24. Move the tubular body to the coordinate origin (align it with the cylinder. Snapping can also be turned on in alignment mode: pivot point, by moving the object, the pivot point of the step can be snapped to the pivot point of the center column); Rotate the starting edge to the positive direction of the 0X axis. The tread height is 192mm and the height is 3650, so the tread number is 3650/192 =19.01(18).

4. Move step: move upward 192mm.

5. Rotate and copy the stairs

Z-axis increment is 192mm, and the rotation angle is 24 degrees (the previous slice is set to 24, and the angle is positive and counterclockwise. ), the number of one-dimensional arrays is 18, and the copy method is instance copy. draw

6. Overlap the steps.

Select a step, add the "Edit Polygon" modifier in the step, enter the polygon level, select an edge, and stretch with a height of 35mm.

7. Thicken the thickness of the step and one side of the central shaft.

At the vertex level, select and move vertices.

8. Pull the rotating handrail

Draw 2D graphics/spirals with the following parameter settings:

Radius 1, radius 2 is set to 850 (slightly less than the maximum tread radius), height is set to 3650mm, and the number of turns is set to 1.2(24* 18=432 degrees, and then divided by 360 degrees,1.2); Set counterclockwise (consistent with the rotation direction of the step).

Set the handrail coordinates to the origin and align with the steps. Move the handrail up1092mm (900+ 192 (the first height)).

Set the radial thickness of the handrail to 30mm.

9. Draw railings

Draw a railing with a cylinder, change the position of the pivot point to the origin, set the angle capture (capture angle is 6.5 degrees), rotate and copy 3 pieces, and adjust their heights to connect with the handrail respectively.

After grouping the four handrails, change the position of the pivot point to the origin again.

Array copy: (the parameters are the same as point 4)
