[Therion] Options for converting splays in my Cave Convertertool

2013-07-20 Thread Footleg
Thanks Bruce, I was not aware of that option to show/hide splays in Loch.

I also never realised that lox models could generate passage walls using
LRUD data. I had only seen it done using plan scraps and over-riding badly
interpolated heights using ceiling height points in my scraps.

Can I add LRUD data to my survey data in order to generate passage heights
when the wall lines in my scraps are used to set the widths? This would be
a good reason for me to accelerate support for Therion format reading and
writing in Cave Converter. Then you will be able to generate LRUD data from
splays to improve passage dimensions in models viewed in Loch. I'll find
you a compelling reason to use this tool yet Bruce!

[Therion] Options for converting splays in my Cave Convertertool

2013-07-20 Thread Bruce
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.
