working with large stl files

working with large stl files

working with large stl files

(OP)
I just got involed with a project using stl part files and what is needed is to cut a solid with this data so far i found a software on www.downloads.com called ctrlveiw 3.1 that will convert a stl to iges a nice software but the translate iges data will take to long for the projects goal
so now i am creating a program that will create  new surface data off the stl within tolerance
my question is does any one know of a program that alredy exists?

RE: working with large stl files

You can import the STL files into NX as faceted models and use them for packaging and cutting sections. If you want a decent model you'll have to do some work to arrive at satisfactory results. As far as I'm aware you're out of luck if you need to analyze volume or assign mass properties to a faceted model.

If you have an industrial design project where you need smooth surfaces then there are other packages that claim with varying degrees of accuracy the ability to surface from STL files. Of those that I have seen some can do an impressive job of rendering a scan into a surface, but it is always the one surface. In order to break up the slabs from edge radii and come back to a properly built and highlighted result there is always some work involved and it is usually a lot of work.

Those of us who occasionally surface from scans which usually arrive by way of STL files do so by cutting sections, smoothing and building curves from that data.

If you simply have an engineering project then your more automatic systems tend to take out the sharp edges. You're probably better to section up your model and work from there in solids if that is more appropriate to the product.

The type of product that you downloaded simply creates a flat sheet for each and every facet in the STL file. The problem being that for even the simplest models the facets are too numerous for practical purposes.

Hope this helps

You are saying "so now i am creating a program that will create  new surface data off the stl within tolerance"__
If you find a solution plese post it.
I need myself help on converting stl to surfaces, so far I had been using Geomagic Studio 6 and a software called FreeForm by Sensable it work ok , but it is time consuming.
Any help would be appreciated.
