One of these is where a passage contains a pit with a second scrap going off at the bottom of the pit...
In that example the lower scrap in included in a separate map, and that map is then included in the upper map using the preview command:
map map5 -proj plan scrap1@s1 break scrap2@s2 preview above map22 endmap
What is the purpose of using two maps here? I appear to be able to do this with a single map containing the two scraps.
Hi Footleg In this example scrap1@s1 break scrap2@s2 should produce scrap1 overlying scrap2 (and is in one map, map5). So yes, one map, two scraps, one overlying the other. preview above map22 places the outline of map22 in map5. I don't think preview allows specification of scraps, so a second map is required. (If I were writing that map definition I would put the preview above first, because in map definitions generally, therion places the object at the top of the list on the top 'layer' in the map. However in the case of previews it seems that therion overrides that convention). Bruce
