The process below will describe how to create a simple rectangular adaptive component similar to the image below.
First step is to go Create Family as show below.
Then select the Generic Model Adaptive family template.
In the empty family place 4 points that will eventually form the corners of the rectangular shape.
Once placed select each of the points and change their type to be Placement Points. These four points will then become the four point that you’ll click in your model to place the family. You’ll notice that as you change each point they will be named starting a point 1.
Now place another four points in between the corners. Change these point to be Shape Handles. You’ll be able to adjust these points in the model to alter the shape of the object.
To create the geometry select three points from on side and click the tool Create spline through Points. This will create a spline spanning the three points.
Now create all four sides as shown below.
Create a point on one of the lines. Select the point and create a rectangle on the selected plane.
Select the rectangle and the four splines and click Create Form on the ribbon. Once created Load the adaptive family object into your Project.
In my project I had set up a floor with 4 columns at various heights. Place the adaptive family by clicking the top of each of the columns in the same sequence that the Placement points were created.
This will place the family. Optionally you can select any of the Shape Handle points and adjust them by the use of the gizmo. This will adjust the sweep and change the shape of the family.
