inroads v8i ss2 ver08.11.07.494 - Cross Section Viewer__Plan View not working

Question

I am able to view cross sections with viewer BUT I cannot get the plan view to work correctly. I am not the author of the the cross sections so I don't know any of the details other than the alg file. 
 When I select a cross sec set and pick the station, the Cross Section View shows me the x-sect but the Plan View goes into the black of space. I am kind of new to this new version of inroads so maybe I have missed something. 
 Do I need to have more than the alg file loaded? I'm thinking I do, but I don't know what it would be. 
 Thank you

Thanks for sending your data. The problem seems to be caused because the ALG file does not contain the horizontal alignment used to cut the cross sections. Therefore, the plan view is being zoomed in on 0,0. 
 If you look at the "Cross Section Set:" field on the top of the Cross Section Viewer, you can see the set name. In the cross section command, the set name is the same as the horizontal alignment name by default (which can be changed by the user, but is not changed typically). The set name for your cross section set does not match any of the horizontal alignments in the ALG. 
 Therefore, if you can locate and ALG that contains the horizontal alignment shown in the Cross Section Set name, I believe the command will work as expected.
