Hi Footleg

Although I have not used your software, and I don’t imagine that will need it with my current workflow habits, that may not always be the case.

I like the idea of what you are doing, and think those four options in your original post seem to have potential uses.

Some comments from your recent post.

>Loch appears to not show splays at all.

Loch does enable splays to be turned on and off.  By default they are off, even if they are present in the data file.

Right click, select ‘scene’, then ‘centreline’ and you can toggle splay visibility.

>Why not use Therion and Loch to create the model (I can almost hear Martin

asking!). Well until I have drawn all my scraps I do not get solid

passages of the correct size. I think Loch makes up the passage

dimensions based on the leg length of something. Certainly not using

LRUD data or splays.

Not quite right. If you set ‘walls auto’ in your centrelines,  (pg 20 5.3.11 Therion Book) Loch generates passage tubes;

1. by guess where you have no LRUD data

2. as per LRUD data where it exists

3. as per plan scrap drawings and ‘point passage-height’ or ‘point dimensions’ where they exist, and otherwise guesses for passage height

My guess is that if UD data is present, Loch will superpose plan shape and realistic passage height – I have never tried it, so Footlegs option to generate UD data from splays will be interesting.  The embedded image is case number 3 above.
