Opening point cloud in SolidWorks

[roldy]

I have a csv file with coordinates of a quarry. When I open up the file there is no elevation showing. It's almost as if SolidWorks flattens the point cloud onto one plane. Why is this happening? Attached is a file containing csv file.

Yes Brad!! That is what I was looking for. I had know idea that was in there. If I can get that mesh and make a surface from it that would be golden.

B05, that's cool looking, where the heck have you been the last hand full of hours, I probalby could have gotten something done today rather than play with roldy's project. Naaa, it's a slow Friday

Yaaaa, that "I see you are only trying to model a small area now" would have been good to know earlier on, it would have resolved a lot of the unit issue the data appeared to have

Hahaha. In to save the day with one comment. I appreciate you djhurrayt helping me out.

This has been a fun and interesting thread. (However, I do think some of these questions should not have even needed to be asked, at least in this forum, as they should have been answered by the surveying team.)

I am very curious. Where is this quarry? It looks very similar to one I know.

This is the Bellwood quarry in Atlanta.

Let us know if you find Jimmy Hoffa there.

Darn work... haha

I don't think it will work well to import the complete tin, so I created a mesh of just the contours in the drawing. The first trial mesh of the complete site was 350Mb, and SW will not like that very much. I attached a dwg with a solid model, but it does not sound like you have a package that can export this to an .iges or .step file for SW. I will post a link to an .iges file or sldprt later. I have to go to site for a few hours now and SW is still working on importing the .iges file created from CAD.

Thanks a bunch Brad. I literally have spent 3 days working 12 hours doing data manipulation trying to figure out how to get a 3D model. You are a life saver.

I would actually really appreciate getting the .iges file since I won't be in the office until Monday. I have SW 2012 at home.

Here is the SW file. I clicked on the wrong file, so this is a solid of the complete model. The SW file should look like the attached image. This is in SW2015. I can post the iges file a little later too. This file is not quite as large as I expected. Without re-sampling the points to reduce the quantity it will be difficult to make the file much smaller. I am not sure exactly what you are trying to do, so it seemed best to leave it as is.

The area you are interested in imported in minutes, so here it is too. I attached a picture of what it looks like at my end too. I didn't check the scale factor, but you can extract a couple of sections to check that and scale if you need to. This only took about an hour or so, but we have quite a few software packages and some practice. You peaked my interest with the point cloud aspect, and I have always wanted to see what I could do in SW with our scanner data. I learned something in the process.

Wow. I really appreciate all of this. I am limited with available software. I may have to stop into work tomorrow and see if I can get into the office to work on this a little.

I actually need to cut a tunnel through the surface. I have the sketch of the tunnel and I created an extruded surface. I used the trim tool to try and make this cut but SW keeps crashing. I'm not sure if there is any other way to do this. I also have been trying to convert this surface to a solid by using boundary surfaces and knitting them together but have had no luck. I have your assembly in my assembly because I have other features to add that are not to be combined with the quarry. Here is the link for the file

Edit: I found a solution. I just extruded a sketch from the bottom to the surface and hid the surface. Now I can do all my operations on the solid.
