Unable to get model Fully Defined

[mattb1969]

I have done some research and I have been trying to get my model fully defined.

I have tried moving things, but i have drawn a blank and now have more problems than I started with!. No matter what I try, I can’t get Profile Sketch to become fully defined and now I have 2 orange lines and a number of errors for the front sketch. 

Can anyone help?

In an early Extrude, Fusion has selected the centre floor panel. Unselect it.

2nd Sketch has a short vertical construction line, orange, needs a dimension.

3rd Sketch, has lost some projections, to make sense of them, I deleted the Extrude just before it.

Manage Lost Projections needs reselection.

Rest has updated without further errors, but the blue lines in the 3rd sketch need attention.

Might help...
