Envisioneer is a versatile tool that will work with all of your design challenges. If your design incorporates a curved wall feature, select the wall that you need to curve, right click and select Curve. Place your cursor on the midpoint of the wall and holding down the left mouse button drag the wall in the direction of the curve. You will notice that in your commander area you have the ability to specify and exact radius and included angle for added precision. I hope that makes your Envisioneer work, one step easier!
