(nuts) Hi folks,
I need a topo model carved by CNC in polyurethane foam (roughly 4" deep, and 1/4 of a circle with a radius of 5.5' (imagine a big pie, and what a quarter of that would look like.) I've got topo maps, and drawings. Anybody fairly local to either of those locations considered. Thanks!

I would like a crack at it, but I am not local. I am in tennessee

Okay,
Local isn't so important to me but I'm trying to keep costs down and shipping these days is getting expensive. If you can send me your email address I'll send you a topo drawing. I'm looking at 10lb polyurethane foam but will consider other materials. Would you like to quote? Please send me your email. Thanks! Patrick

I'm in San Antonio. shoot me a message, the best way to do it is download the city DTM (digital terain model), then create your surface in Autocadd Land desktop, then export the file. I did this for the UIW University when we did a dorm project for them.

BTW, I work for Civil Engineering and Land Surveying company.

Hi Joe,
Call me please (210) 225-7066.
I can send you a topo map by email (about 4MB). I'm looking at a vertical scale of 1" = 200', thus the model could be cut from a 4" x 48"x96" block of foam. I'm considering using General Plastics FR-7100 12lb rigid open cell polyurethane.

Does that work for you?

Does anyone know how this type of foam would work for a lost-foam casting? I was just thinking if it would work well I'd be interested in purchasing some of the drop from the RFQ awardee.

Patrick,

We have done several large topography models as well but we are in Ohio. If you need more quotes, please send me the data also.

[mctoxey]

Hi Joe, Thanks, I'll send you data too to your email address.

I mean, Doug, not Joe, sorry!
Thanks,

here is the google earth of the area, also as you know it falls on 4 quad maps, which mean 4 different DEM's i have downloaded them and will generate a surface from the DEM's to see what type of terrain we get.

Hey Joe, What software are you using to generate the terrain from the DEM ? I've been messing with the free version of BlackArts but am not sure if it will do want I need, unless I pay for the full version.

Thanks,
Todd

I use AutoDesk Civil Design 3D 2007.

Here is a sample of the Benicia DEM.

I would also like to quote on this project.

Ohhhh~ I get it. This is a closeup of the straits between the two bays....A thing of beauty!

Hi Joe,
This is beautiful work, but I need to move forward with this project. Can you call me please by Friday, April 20th? I'm going to blow the deadline if we wait longer. Thanks!

PU is pretty impervious when you want to get rid of it. Solvents don't eat it, and heating it creates toxic fumes that send people to the hospital. EPS would be a better choice.
