I am a beginner for fusion 360. I would like to sketch the enclosed trapezium. What is the simple and best way to do it? Pls let me know the step-by-step. Thanks. — simon

Hi,

Please find the screencast here.

Note: The construction line is drawn by snapping to the center of the line (inverted triangle indicates midpoint of line).

Adding to this, you can use temp/construction lines at the ends to specify the differing edge lengths. Alternately, you can set specific angles at the corners. Feel free to overlap lines and clean up after with the trim tool, a real time saver. Building on a center construction line is really helpful for this type of sketching.

Here's a quick way staring from a rectangle. Few less constraints in this version, always keep the symmetry constraints to a minimum as they can slow the sketch solver.

Just noticed I forgot to add a vertical constraint to the construction line in the screencast.
