To save the 2d projected sketch, right click on the project sketch under the Sketches folder and save as a DXF. After you move the body, you should now be able to see the extruded body and the projected sketch. In order to see the projection, you have to move the body with the move tool. In your sketches folder, you should now have two sketches: one for the original body and one for the projected sketch. Press okay in the Project menu and finish sketch. You should have the body selection filter selected and the projection link selected in the Project menu. Select the body again for the geometry section in the Project menu. While the face is selected, press the “P” key on your keyboard. Finish the trapezoid sketch and extrude it (the distance doesn’t matter you just need to extrude it for the next step).Īfter the body is extruded, click on the top or bottom face of your body that is the trapezoid shape. At this point, you should have the trapezoid shape. Then, connect the parallel lines together. The parallel distance between the lines should be the length of your part. When you sketch the splines, they should be parallel to each other. Not sure if you know this, but you can right click the spline and get the exact measurement. To sketch this, you need the length of your part and the measurements of the front and back-end splines. You should not have two curved lines/ splines at the end. This is why your meshmixer shape is incorrect. This is going to be counterintuitive, but the shape you need is a trapezoid. The part I was making was laser cut flat and then formed into the curved shape with a heat gun. I had a very similar situation for a part I was creating.
