Creating a plane perpendicular (90 degree) to a line on a sketch plane

[schengnz]

I have used Fusion360 for a few years now, but I ran into a simple problem that should be simple but I could not solve.

I have created an example to illustrate the problem.

We have a Plane A. On plane A I have created a sketch with a few straight lines.

What I want to do is to create a Plane B that is perpendicular to Plane A that goes through one of the lines on a sketch on Plane A. 

I could not figure out how to do it. I tried using Plane at Angle and select the line and specify 90 degree, but it does not seem to  work as expected.

What is the right way to do this? Thanks.

The angle of the plane being created is always taken from the Origin plane.  Your plane is not parallel to the origin so you need to run the Plane at Angle construction command, select the line, then select the plane you want to be 90 degrees to.  This will give you the existing angle to the Origin.  Then just add your desired angle to that, in this case 90 degrees.

taking a measure from the first plane by selecting it as John is showing is the easiest/fastest way, but it is static.  So the perpendicular relation ship won't be maintained if the original plane is changed.  On way to make the relationship parametric would be to us a plane along path instead-

you can also add the parameter from the first plane (d1) to the second plane angle value-

Thank you! I learnt a few things from both of you today. Thank you!

I also found a third solution. It looks like Fusion now supports 3D sketch (which I have never used). One solution which works (but not as elegant) is to add a 3D perpendicular line to one end of the line in the sketch, and then create the plane using "plane with 2 lines".
