Not really enough detail there to work on. It could be any number of things.

Max version?
System Specs?
Scene details (system units, object size)?

Can you post the scene (zipped) so we can try on our systems? This will help determine if it’s your system or the scene which has the problem.

first thing that comes to mind in cases like this is scenesize ...
if it’s really small then things like this start to happen.

Hi, thanks for the quick reply.  I scaled the object up and it looks ok. Must have been too small? System Units was 1 unit = 1 meter and display units was millimeters.

Perhaps better to have the System and Display units the same? Max doesn’t like very small numbers (1mm = 0.001M) - try not to use more than 2 decimal places, if you need more regularly, consider changing your system units.
