Example 11

This is a continuation of Example 10.

Now we are going to make an stairway using the cube. I will start by loading the Example10 file and work with the Control Tower to add stairs and also a fence around the top as shown here.

Since this needs a MSO macro type I will first convert Example10 to a MSO type macro.

We will need to add three more modules to the previous macro.

This shows how the stairs need to be made.
  • The altitude is the altitude of the first
    module, or 8 meters.
  • The stair base will be placed at 8
    meters from the wall.
  • This distance will be the distance
    to be used to tilt or skew the cube
    in the special object options.
  • Since the base is 16 meters wide the
    stair base will be placed at 16 meters
    from the center.
This option will make the cube skew to the right.
This table shows the size of the stair. You will get a better effect when using a stair width less than 1/2 meter and don't forget this macro is based on an scale of 0.5

 

Finally we will make the hand rail using the bridge. The width of the bridge will be the width of the stair, that is 3 meters.
The stair handrail will need to be rotated 90 degrees
to head to the right position, using the MSO maximizer option.
To finish the object we will add a fence on top of the first module.

The altitude of the fence over the ground is 8 meters which is the altitude of module 1.

The height of 2 meters is the height of the fence.

 

The first thing you should do is to draw the layout or contour of the fence. Each ending point is represented by a red circle. This option only adds the horizontal line between points. To draw or place the vertical points you must first select the Place posts option and start adding the posts to their positions.

Vertical post are easily recognized
by the yellow points in the graph.
