Adding tangent circles and constraining them to stay tangent
- Type B Edit, Enter. Select the constrained block and click OK to open the editor environment. This block has geometric and dimensional constraints applied. To make things more interesting let's draw a line that goes diagonally from one corner to the opposite corner and then draw a circle. And let's use the three point method to construct the circle. Go down here to Object Snap. And toggle off all the modes. And then toggle Tangent mode on. Click these three lines to establish the three points of the circle where it's tangent at each intersection. Let's do that again. Circle, down arrow, three point, and then click one, two, three tangent points. Let's test the block and see what happens. The circles and the diagonal line are left behind. They don't seem to be related to our dynamic functionality yet. Close the test block. In order to make things stay connected we have to apply geometric constraints that keep the circles tangent to the lines. So I can select this line in this circle.…
