Calculating and using weight of individual parts and an assembly Note: each type and nominal size of material may have a slightly different density, so one must do a separate density calculation for each type and nominal size of material. However all pieces of the same material, regardless of length will have same density. Unless noted, all commands are in new UI. This example uses a C8 x 18.75 x 12 C-Channel to calculate reference for all C8 x 18.75 Channels. Bold text represents IronCAD menu choices. 1. In IronCAD Common/Units , change all to customary inch units (inches, degrees, mass in pounds, density in pounds per cubic inch). 2. Under Round IronCAD Logo (Extreme upper Left), choose Tools/Options. In Options, change Precision displayed ... and Dimension precision to 4 decimal places or more. 3. Bring in a 12 in long piece of same part, then measure volume. in Tools/Analysis [Must be exactly same type & nominal size]. Use Compute button to initiate actual calculation.

Unformatted text preview: Result of sample comes out to be: C8 x 18.75 x 12 = 66.2980xx in 3 ]. 4. Manually divide weight per foot ( Ryersons ) by volume to determine density of the material per in 3 [e.g. 18.75 lbs. per foot / 66.980 in 3 = density of .2828 lbs. per in 3 ]. 5. Choose Part Properties/Material for each C8 x 18.75 part and enter Mass Density. [e.g. .2828 for each C8 x 18.75 C-Channels]. 6. After all parts have been modeled to proper size, and density has been entered in Part properties of each, repeat Tools/Analysis process to determine weight (mass) for each part. Note: default Mass Density of .252891 for any part is similar, but not accurate. 7. Once weight is determined for each part, Choose Control-A (All), the choose Assembly/Assemble, then with assembly in yellow, Choose Tools/Analysis again to weigh assembly. Record that value as a Global note on the drawing....
