Bridging the platforms

Course 8- Bridging the platforms

0:04 We previously created several platforms as the base of our playground.

0:10 Now let’s create a bridge that will join our entire playground together.

0:17 To create the arcs that we’ll need for this bridge, we’ll create a large box first.

0:23 We could draw the arcs directly, I just find it’s often easier to create a surface or box to work on when using arcs, as they have a tendency to snap all over the place

0:35 A surface helps control them.

0:40 Draw a large rectangle between these two back pillars, and push it to the opposite edge of the platform.

0:48 Now I’ll push the bottom to make sure it’s lined up with the bottom of the platforms we are bridging.

0:54 I’ll use the 2-point Arc tool to create an arc between these two bottom endpoints, pull it up and use a bulge distance of 6 inches.

1:06 Something that’s a nice gentle curve.

1:09 Then select the arc we just drew by one of the endpoints.

1:13 That way we can move a copy of it, lock the blue direction and reference the top of the platform for our distance.

1:22 I could also just type 2 inches if I remember the depth of the platform, but this is another example of how you will usually just use inferences once you have some known geometry.

1:36 Let’s carve the top away with Push Pull, and then double click with Push Pull on the lower surface to cut away the same distance.

1:47 We better group this bridge now.

1:49 Remember that we want everything in our model as groups or components.

1:54 I don’t plan to copy this bridge, so a group should be fine but you might choose to make it a component so you can name it and have it in your component library.

2:09 Steps:

0:00 - Draw an arc between the base endpoints with a bulge distance of 6 inches. - Copy that arc upward to the top of the platform. (2 inches) - Push Pull and cut away the box leaving our bridge. Make the bridge a group or component.
