[Therion] Displaying some (not all) cross sections

[Andrew Atkinson]

To add the arrows to the sections use 

-context point section

See page 26 of the book. It might be sections not section, I'm on a phone so cannot check my data.

For reducing the number of sections, I've not tried this, but maybe 

-attr <name> <value>

Adding this to some then turning them all off and then only the attr back on, or vice versa may work. This assumes you can use symbolhide/show with an attr. Page 36 says they can be used in macros, so if all else fails macro writing might have to be done.

Good luck

Without the arrows, there is no way to clearly show which scrap goes with which section line.  When I leave out cross sections, the arrows remain.  Is there a way to designate the arrows as part of the "sections" group?
