Re: [Therion] How to properly scale xvi for using as a background image for drawing

[Marco Menchise via Therion]

Yes, I'm using Topodroid.

Topodroid sketches are exported using a scale factor of 39.37, so to create
a proper .xvi I had to use the following thconfig (let's say survey,th
contains centerline data and splays):



source survey.th
layout topodroidlayout
scale 1 39.37
endlayout
export map -proj plan -layout topodroidlayout -output background.xvi



After that I'm able to use the generated .xvi as the backround for the
Topodroid sketches in xtherion.

Thanks to Marco Corvi for the explanation.

[Therion] How to properly scale xvi for using as a background image for drawing

[Marco Menchise via Therion]

Hello,

is there a simple way to scale .th2 scraps to make they perfectly match the
scale factor of a .xvi file used as background image in xtherion?

I want to edit a set of scraps (which are contained in a single th2 file)
while having centerline and splays as a background image. So I usually
generate the .xvi file from centerline data and load it as a background
image of the scrap in xtherion. If the scraps don't have the same scale
factor of the background I'm not able to superimpose them and edit the
drawing.

How to make they match? Should I edit .th2 files by hands and do some
calculations?

Could someone please clarifiy how Therion manages scale factor of scraps?

My scraps usually contain stations so I'm quite sure I don't have to change
the "-scale" option of the scraps.

Thanks,
Marco

Re: [Therion] Therion and DEM

[Marco Menchise via Therion]

Hi,I also tried to lower the DEM accuracy by cutting digits after the point
but I got same error:  line too long. In my case I have only 3 digits.

I would know if it is a Therion limit and if it is somewhat possible to
overcome it by, for example, recompiling Therion.

Hello Torsten, thank you for the reply.
Unfortunately (or luckily, I don't know) I don't have windows so I can't

[Therion] No passage walls converting .plt to .lox

[Marco Menchise via Therion]

Hello, I have a Compass .plt file which I am able to display with Loch. I
happily see station names and passage walls.

I'm trying to generate a .lox file to display with CaveView on the web.
CaveView needs .lox format.

To do this, I import the .plt in Therion then export the lox model enabling
all features (walls, splays, etc.), but I get no walls in the final file. I
tried to generate a .lox model from a test .th file written by hand and I
was able to get all the features.

Am I missing something?

Re: [Therion] Therion and DEM

[Marco Menchise via Therion]

Hello, I recompiled Therion with a new limit and I generated the .lox
model. No "line too long" error anymore.

Unfortunately, I wasn't able to overlay a .jpg image. Therion overlayed
only part of it over the whole DEM. Sligthly changing calibration data
produce even weird result ..

I'm starting tho think that there are some other constants to tweak
somewhere else.

I cannot attach the model because it is very large (about 200M).
