[Therion] Extended elevations - development snapshot (commit 6860f82)

[Bruce Mutton]

> there is a possibility to specify reduction ratio for extended elevation
(0 = vertical, 100 = normal left/right) - just use "extend <number>"

 

I have a project that is just perfect for this, but have not been able to
make it work.  I expect I have not understood how the syntax is intended to
be used.

The statements below relate to only a small part of the selected survey
centreline, and cause this error

":\Program Files (x86)\Therion\therion.exe: error --
Extend-DwarfsDoorElevEXT.th [120] -- station doesn't exist - 1"

 

If I remove the group endgroup pair, the project compiles just fine, however
this branch (and the whole extended elevation) is compiled full size without
the 85% reduction specified.  The 'extend 85' statement is ignored.

Also there seems to be a problem in that a group block is somehow cancelling
the station-names specification (whether or not it is moved inside or
outside of the group block).  I have never really used group blocks, so am
not familiar with their limitations.

 

centreline 

  group

    station-names []@D-K6 #DwarfsD-K6-Stream.th

    # now foreshorten this passage so station 13 appears near to station 2
(the red branch in the diagram below)

    # they could have been a loop, but the surveyor did not close to the
same locations

    extend 85

    extend left 1

  endgroup

endcentreline

 



 

 

If I try

    extend 85 left 1

 

then I get the error

"C:\Program Files (x86)\Therion\therion.exe: error --
Extend-DwarfsDoorElevEXT.th [120] -- unknown extend flag - 85"

 

BTW I assume the reduction and the three-station path ignores will be
reported when log extend is added to the thconfig?
