Across a language barrier, I am Swedish, I'm lost in some of your
jargong/techical terms . I do wish there could be some place on the net
one
could find translations and definitions of proffesional terms and jargong.
Wikipedia/Wiktionary might be usable.
Anyway - I use Triforma and Architecture and model most in 3d and then
"calculate" the cuts for plans and elevation. The "stair maker" in TF is
awful and there is a new tool announced for Athens. And Structural have a
tool for stairs + handrails that is said to be ok for "industrial" stairs.
But a scenario with setting up base data + "rules" for a stair in a
spreadsheet and having that linked into ustn and "drivinging" the
3d-geometry, for later TF 2d-"calcualtions", is a good one. Be it with
DDD(=dimension driven desing), Feature Modeling or Generative Components
(even if that probably is to use cannons on mosquitos), or even custom
linestyles.
Feature Modeling has been around for a while in ustn v8,9. (TOOLS>FEATURE
MODELING). And you can do amazingly much in 3d with custom linestyles -
thinking of handrails.
