Triangular DC ?

eselick

Hi
Does anyone know how to approach creating a component with parts that don't meet at 90 degrees. In my example, the thickness and width of the parts would be fixed but the intersection angles would change based on the overall width and height of the parent component.

I want to use this for adding trim to the gables of the houses I model and wonder if this is possible with DC's?

Thanks

Hi

yes...

Make the shape out of a group of components, where adjacent edges are hidden, adjacent planes are deleted. Triangles are position on the changing axis so hypotenuse changes with sides. Position the axis so that changes go in the desired direction, Refer to my dynamic roof frame in the warehouse.

In theory any shape that can be contain, by pulling a more complicated form apart, thus it can then be manipulated.

Then the fun begins....
especially when changing the attributes. one has to make the changes in reference to the parent axis, if it flies of into the never never, then undo as you are probably in a child environment and change level. For the pitched components I found it easier to build and alter them in a rest position, the rotation values all at "0", otherwise one can get lost within the referencing

To trim the edge, you must work with three parts in one component : the center (rectangular) and the edges (triangles). How said pcmoor, you must hide some edges and your component seems to be only one part.
Now, you must script the size and place of each part, using the global component angle and length. The length of the edges are calculated with the tangent of the angle and the global width, the lenth of the center with the total length minus edges, etc.

Here is an example :
Test_DD.skp
You can rotate and scale the component (when you rotate, it does'nt update the shape, you must scale or click on it with the "interact" tool)

Of course, there are problems when you're near to the horizontal or vercital, because the tangent become huge for one edge.
