Problem picking points or anchoring points with solution

[cappleby1]

Hello fellow Polyworks users,

Recently I had a problem that was really causing a slow down in my work. Basically I had been having difficulty picking points using the tool that looks like a pencil. The points link to a different location on the point cloud then where I clicked at. The point cloud density is good but the picked points were way off from where the pointer is. The problem happens usually when using a point cloud.  For example it will happen when picking points for the alignment or for surface comp points or even just trying to use the anchor method.  I did not changed any settings to my knowledge.

After emailing Polyworks I received a suggestion that worked:


Hello Chris,

I have seen this problem before when a PC graphics card driver is not up to date.  I would recommend first finding out what type of graphics card you have (typically NVidia) and going to the manufacturers website and downloading the latest driver.

If it is an NVidia card, you can first try a "Partner Certified Driver" (this is one that PolyWorks states works well).     http://www.nvidia.com/object/quadro-certified-drivers.html


If your graphics card is not in this list, the latest driver available should work.


After the update my picker was working again.  I would never have figured the driver could cause this issue because it was working before.  I guess is that my addition of a second monitor made it go haywire.  Well either way it works now.  Hope this info will help some of you out there :D
