Convert 2D topographic surveys + DTM files to 3D models
-
Yup, Wayne, for the seond look I also discovered the difference. Indeed there have been a couple of cases here with people who would have been happy with a solution like that.
John: sure I could - I'll collect a nice set of example files (not today though
) -
I already have "text2d3d.lsp" that does something of this sort... reading 2d levels text and makes a 3d points cloud from it in AutoCAD... I wrote it a year or so ago, initially specifically for someone, so I won't publish it as a 'spoiler'... but you can always pm me if needs be...

Tig that's great, you should publish it, I don't see these free options as spoilers.
I assume your script requires access to AutoCAD to work (please correct me if I'm wrong). My software runs online (OS independent) and as such doesn't require AutoCAD to perform the conversions. Personally, I work using Vectorworks (MAC), but the files I receive from our surveyors are .dxf.

Hi,
This looks great to me Wayne i sent you an e-mail asking if i can have a go with it. How much will the software be to buy ?
Cheers

Wayne,
Sounds good, will it work on 2d ordnance survey map dxfs as they often have the height data marked on?

Jon,
It should work fine with the OS data, do you have an example to give it a spin with?
If not, I can send you a couple of different file types over and you can try it for yourself.
Just drop me a line direct to mr_ashley@little-something.com and I'll give you a login.
Cheers,

Well yes, there's definitely scope for developers to play around with here. In the new year I'm going to tackle getting external building data into the model, alongside some of the more typical features trees/lighting etc.
But such ideas throw up fresh problems; at the moment it does a dull job, in a fast and uncomplicated manner.
...but you know, I'm just waffling now!
Back on topic:
Besides little-something.com, cloud.rb and Tig's LISP script, how have other people been getting their topo and raw data into Sketchup? -
I've been using free DEM's for existing general terrain when I need it. Or else importing Google Earth terrain if I don't need it to be very detailed. I also will make topos by hand quickly sometimes if needed. So far I've never been given cloud data type stuff. I think I don't work in an environment that I need to be dealing with that stuff.

Thanks to all those currently giving the software a spin. For a small few of you, there appears to be a bug in the Topo conversion. I'm working on a fix and testing over the weekend - so if anyone else would like to trial the software, I suggest holding off until Monday/Tuesday.
As for the bug...
as Donald Rumsfeld once said"...there are things we know we know. We also know there are known
unknowns; that is to say we know there are some things we know we
don't know. But there are also unknown unknowns -- the ones we don't
know we don't know." - At the moment it is a known unknown, but I'll keep you informed.Or better yet, to quote from "Airplane"
"...looks like I picked the wrong week to quit sniffing glue!" (it was something like that anyway)

WayneI still won't make it 'public'... but if anyone wants a 'free' lisp-routine to make 3d points simply from 2d [m]text within AutoCAD [or something else using lisp], then they can PM me and 'discuss' it...

Thanks for your patience, subscriptions will be back open this evening.
