how can I create a 3D channel with varying height and width

[Elahotahari]

hello guys

I am new at AutoCAD, so I've got a question. I want to model an open channel which its height is descending and the width of it widens from upstream to downstream.

I will attach the top view and front view.

can anyone help me with this?

I want a solid to export as a stl file to work with Flow3D.

thank you all.

- Draw both your 2d shapes using a closed polyline

- Extrude both your shapes to the correct 3rd dimension

- Rotated3d one you your shapes and correctly place it intersecting the other shape

- Use the intersect to merge both 3d shapes into 1 shape

- Use the solidedit command, to shell out your 3d in to create your open channel
