GSI file to AutocadLT

[telboy]

I have purchased autocadLT a few weeks ago. My problem is I use Leica total-stations 1105/1103 using my PCMCIA cards to collect data in .GSI format. Is there a method or software to put this into .dwg or any other format that Acad can recognise and allow me to download direct from my card other than manually put each coordinate in?

I assume a .gsi file is some type of text file that you can read and make some sense of. If so, you could convert the data into a format (say with a text editor, Excel, etc.) that would be useable in a script file (.scr extension) to issue series of commands into AutoCAD. I've done this with lisp but LT version doesn't support AutoLisp. You could have a block, say called "surv_pt" that has attributes for point number, elevation, description. Also say you want block scaled by 20. Starting at point 100, script file would then look something like:

Multiple
-Insert
Surv_pt
x1 y1 z1 20 20 0 (responses to block insert prompts)
100 (these 3 are responses for attibute prompts)
123.67
BC Mon
x2 y2 z2 20 20 0
etc......

As I type this I see it would be quite a pain to create this file. Now say you just want to put a point in the drawing. Much easier script file to create:

Multiple
Point
x1 y1 z1
x2 y2 z2
etc.....

If this looks of any use to you and you have questions, let me know.

Good luck!

The gsi.format can be converted by means of a utility which LEICA supplies to an IDEX file. This is basically an ASCII txt file formatted simillarly to what CARLB was describing. I down load that directly into my CAD or Survey software which reads the point name Y X and Z values
It is a bit tedious sometimes especlially if the observed co-ordinates are not in proper orientation. It is thus important to observe in proper orientation.

I suggest you contact your nearest LEICA agent for details on Software and conversions. Leica has a package called LISCAD which also does all you want with CAD. It is unfortunately expensive.

The conversion software I mentioned earlier should be supplied as part of the instrument supplies and thus free.

I hope this helps. Let me know if you want more help.
