    3d PDF

    Simlab Composer is not free (there is a free version but it does not save 3d pdf), but its pretty reasonably priced. Unfortunately they don't have a plugin for FormZ yet, but its possible to export to a compatible format. SolidWorks does have basic 3d PDF export, but for anything more advanced there is a separate application for more $ to get the additional functions.
  2. The lack of thickness will make it difficult to capture the edge. This would make it difficult to get a crisp edge regardless of scanning method. I'm not sure what would help aside from fitting a piece of thicker material to it. Maybe putting some tape in spots along the edge might help?
  3. Hi Gyro, AGI Photoscan might be a solution but it does require a lot of pictures to build a quality model. If the model only needs to be a reference you might be able get away with fewer pics. Shiny or reflective surfaces can be problematic. Spraying with dulling spray or paint can help with that although that in many cases that would not be an option.

    3D scanners and FZ

    Have not seen that one before, thanks for letting us know, have to check it out

    3D scanners and FZ

    I do think photogrammety has possibilities, even where greater accuracy is required. Unfortunately there is no "turnkey" solution there, or at least none that I am aware of. It's possible to research and build a system that could meet one's specific requirements.

    3D scanners and FZ

    There are a variety of hand held units that use structured light and are probably accurate enough for your needs. Take a look at Artec and Creaform. Greater accuracy is possible from fixed systems, tripod or table mounted, and could be structured light similar to Evatronix or laser, such as Faro or Romer scanning arms.

    This really depends on your needs ... Accuracy requirements will dictate which system(s) would be appropriate.

    Form Z to 3D PDF

    Simlab Composer can generate 3D PDF and WebGL from FormZ's export formats.

    HELP with .sat format

    JL it is good you brought this up ... have to watch out for this.

    HELP with .sat format

    I have tested this in other applications. Its an ACIS v26 file ... it is a newer ACIS version that is not compatible with any applications I have. I suspect that is the issue with your older FormZ as well. Here's the header info from the file: 10 cadwork 3d 12 ACIS 26.0 NT 24 Fri Jun 23 14:28:23 2017 Looks like Cadwork is the application that created it: http://www.cadwork.com/indexL1.jsp?wsid=675967&now=1498232629307 There's a demo available, maybe you can use it to convert to a different format

    Any way to create a bas relief?

    Ken, Are you indicating that any application using 16-bit displacement is not sufficient for your use?

    Any way to create a bas relief?

    If you can render out a depthmap (greyscale values based on distance from rendering camera) it could be used in the Displacement tool for instant bas-relief. I'm on a much older version of FormZ so perhaps rendering out a depthmap is possible in a newer version. If there is no render to depthmap available, it can still be achieved as follows: - Set rendering camera to ortho/parallel projection (should be set like this for depthmap too if its available as a render option) - Apply black to white gradient map from the side of the objects, 90deg from rendering camera direction - Consistent mapping for multiple objects (may need to join or group for this) so the gradient range goes from the closest object to the furthest object from the rendering camera. - Positive/Negative bas-relief can be created by inverting gradient. - Use ONLY ambient light for illumination.

    Mesh to bitmap

    This is a good work around for applications that don't have a ZBuffer (depth) render. However, if Teddydog looking for 16bit greyscale data (the format for DEM) this would have to be interpolated (ie Gaussian Blur) from the 8bit greyscale resulting image in Photoshop or other application that can work with 16bits/channel.

    point cloud

    Malc, You mentioned that the file might be 2.8Gb, which might easily contain tens of millions of points. The RCP and RCS files are proprietary to Autodesk, and are a relatively new format. It is likely you will need to get these files converted to a common point cloud format. If you could get the data converted to a common format, there are very few applications that will read a file this large. If your client actually did the scanning themselves, they would probably also have the software to translate it to a different format, break it into smaller sections, or down sample the total number of points, so you could work with it. If you will be handling more of these files in the future, you may need a dedicated point cloud surfacing application like Geomagic, RapidForm, Polyworks etc. There are a few applications that are architecture specific (I don't have any names off the top of my head) that will let you locate your data according to GPS or other coordinate systems. Meshlab (free) can be useful for some point cloud related work, but I have found even the 64 bit version runs into some difficulty when there are millions of points.
