Greetings! We are trying to build a trophy part. We will build it using rapid prototyping. To do this we have designed a trophy in ProE (and in Inventor 7). We want a 1x2 brick with a flat plate on top of the brick and the trophy on top of the (...) (20 years ago, 5-Nov-04, to lugnet.cad.dev)

Hi Don, How are the updates going to ldglite? I'd like to test it with LPub before I release a new version. I've got it all wired in for construction images and PLI and it seems to work well. I'd love to have -mf and -mF soon. Kevin (20 years ago, 29-Oct-04, to lugnet.cad.dev)

(...) The 4/3 is the aspect ratio of the POV generated rendering (matches 800x600, 1024x768, 1600x1200 etc.). If you for some reason want POV to do a high, narrow (or low, long), rendering this factor has to be changed. It's often easier to do a (...) (20 years ago, 26-Oct-04, to lugnet.cad.dev)
