Course 13- Steps

0:03 Since we’ve just created one way to climb up to the platforms, let’s create another.

0:09 Near this side of our playground draw a rectangle that is 12 x 45 inches, which is the width between our pillars. Pull it up by 1 inch.

0:23 We are going to copy this step so let’s make it a component, then select and move it from a corner to a corner.

0:35 The height of this platform is 32 inches, which means we could copy our step down by 8 inches, array it 4 times...

0:46 ... and with our 1 inch step height, this would result in a nice 7 inch distance between the steps, starting from the ground.

0:55 Knowing that we’d create some steps is part of why I chose that platform height.

0:60 However, what if we did not know exactly how to space these steps?

1:06 Let’s create this spacing a different way.

1:10 So we have our top step, aligned perfectly with the platform.

1:16 To determine the spacing between the platform and the ground, one method we could use is an external array.

1:24 With our step selected, I’ll move it from somewhere on the top surface or edge, make a copy and lock the movement in the blue direction.

1:33 Now I can infer to the base of the pillars which I know is on the ground plane.

1:38 Then I can simply experiment with how many copies to make. I could try 3/ or 5/.

1:48 To measure the distance I do need to switch tools which does stop the array function.

1:55 5 copies creates a spacing distance of about 5 1/2 inches which isn’t what we want, so I’ll undo, create the array again with 4 copies and this gives us a distance that we like.

2:11 The ability to create arrays is so simple and fast that it’s easy to experiment.

2:21 One more method for testing distances is to divide a line.

2:27 Draw a line from the top of the platform and lock it so we can draw to the ground plane.

2:34 Then choose the selection arrow and right-click on that edge and choose ‘Divide’.

2:41 Now we can move the mouse cursor up and down on that edge to divide it into equal segments.

2:49 Pausing for a moment will display the number of segments and the distance so we can easily see what the different length segments are.

2:58 Click to accept any of these results which divides the original line and provides endpoint inferences we could snap to.

3:14 Ok, let’s return to our steps.

3:17 We could move one step out 10 inches and then use that step to create an array…

3:33 ...or we could simply move several steps at once to 10 inches, then move the bottom 2 steps also at 10 inches, and then the last step.

3:46 Either way works fine.

3:55 Steps:

0:00 - Practice making an external array with our step at different spacing heights. Ultimately we are using 8 inch spacing with 3 copies. - Practice drawing and dividing an edge if this technique is new to you. - Move each lower step outward by 10 inches.
