Cadfil Expression Evaluator

HelpCadfil Help contents Home


In many dialog boxes in Cadfil numeric inputs are required. Behind all these dialog input boxes sits the Cadfil expression evaluator, so instead of entering 100 you could enter 99+1. That might not sound that useful but if you have a mandrel of diameter of 374.578 and you are asked for the radius then 374.578/2 is easier or if you know the value is 22.5 inches but you need mm you could enter 22.5*25.4. Complex expressions can be provided if you want e.g 23.4 + 38.4/5 - SQRT( 77.2) where SQRT(77.2) is the square root of 77.2. All of the Mathematical functions and operators you might find on a scientific calculator can be used, full lists are given below. This feature and help topic are new at Cadfil Version 9.48
