English Density units in SolidDesigner 5.1

[Mike Swartz]

Here's a workaround for you inch/pound users in SolidDesigner. Version 5.1 (and 5.11) will output mass in kilograms per centimeter when you are working in inches and pounds. Create a 1 inch cube with a density of 1. Measure the mass of that part. Take the result and place it in the factor part of mass units. For a more permanent work around, you can put it in your startup. units 36.127292: LB

[Mike Swartz]

Here is more information on mass calculation. It seems parts created in inch units on SolidDesigner revisions prior to 5.1 will calculate correctly.

[Fleet Hamilton]

CoCreate says this will be fixed in rev 6.0. In the meantime ... any part created with the correct density set as the default will measure correctly. The problem occurs when you change the density. Load the lisp routine below into SolidDesigner for a cooler fix. I'll issue an altered version of this after rev 6.0 arrives.
