Assistance with tangent curves

Good day everyone,

I'm trying to draw up some curves for an alignment that is 900 ft in length. The beginning line segment is 100 ft while the ending line segment cannot be under 200 ft, both segments are parallel to one another and are offset 10 ft with the beginning segment on the right side. I need to draw two tangent curves between each line segments. I'm still new to Microstation and would appreciate any assistance anyone can give, thank you.
