In my recently completed Vancouver Airport scenery, runways and aprons will not show in TopDownView unless the altitude is set to 30 miles or I remove a macro of a radardome. I converted this radardome macro from ASD2.1, and after a few adjustments, the radardome shows okay in the scenery and is representative of what is there in reality. I would like to retain this macro if possible and would therefore like to correct the coding so that TopDownView shows correctly.I have attached a copy of the API file, I would appreciate if somebody knowledgeable could please review this file and see if they can cure the problem?NigelVancouverI have attached the text below since I am not sure whether the file is attached;ASDesign Compatible

Iam not a scenery designer and don't have a clue about it Nigel but I have similar problem with add-on scenery from Gary Summons and in his support forum he says that this problem happens with large texture files.Perhaps a visit to his site will help.http://www.uk2000scenery.bizland.com/puplic/index.htmRgds

Hi... Have you tried viewing your ground objects while in 'Cockpit' view and viewing straight-down out of the bottom of your airplane ( menu? I've found that 'cockpit-view-straight-down' shows all added objects and you have linear control of altitude instead of the huge jumps that occurr when using 'Top-Down' in the View manu.J.R

When I ported my ASD created scenery for FS98 into FS2002/4 it caused several lockups. By tedious elimination of BGL's and then individual components I traced the problem to three ASD macro's - none of which seemed to contain any "unusual" code. I rebuilt the objects in GMax rather than mess around with the SCASM code so I never did fully trace the offending bit of script. I suspect it was inside the MIF call - either the crash code or the SetVar values..BTW I notice that any default ASD 2.1 buildings (those available from the Hangar or Building icons) seem to hit frame rates a lot in FS2002/4.boneshttp://fsaviation.net
