• aPriori 2019 R2 contains a change to how assembly costs are calculated initially. Assembly subcomponents that have not yet been initialized (costed) will display a value of 0 in the Finish Mass field of the Assembly Details tab. Previously, the mass was estimated, assuming the material density of a common steel material, in order to estimate pick-and-place assembling costs for the component. Therefore, assembly pick and place costs no longer will be estimated for assembly components which have not yet been costed. Previously aPriori estimated pick and place handling costs based on the mass the part would have if made of the assumed steel material. Now no values will be computed or displayed for Finish Mass or any Pick and Place costs until the component actually has been cost with a specific material (or if a Finish Mass value actually was specified for the component using the BOM Loader capability).
