PRECISION VALUE CONTROL IN BASE QUANTITY, ITEM QUANTITY AND MASS

[ashiqueV3N9V]

it would be great if we can control precision values of BASE QUANTITY, ITEM QUANTITY AND MASS in inventor. due to the minor variations inventor shows roll up errors.

@ashiqueV3N9V this can be done in part list. Do you prefer to have the similar setting in BOM dialog? Thank you!

certainly! When dealing with large assemblies, managing bill of materials (BOM) can be challenging due to slight variations in part dimensions or mass. These variations often cause parts to appear separately in Autodesk Inventor or lead to roll-up errors.

i hope adjusting precision settings can be solve this issue. By setting a specific precision level—such as rounding dimensions to a certain decimal place or removing decimals altogether—you can ensure that parts with minor variations are grouped together in the BOM under a single part name with the correct quantity.

For instance, imagine an assembly with two frame parts: one is 100.15mm long and the other is 100.18mm long. Currently, these small differences cause them to be listed separately in the BOM. However, by setting the precision to zero, both lengths would round to 100mm, consolidating them into one entry with a quantity of two.

if it works i think this approach simplifies BOM management and reduces the time spent resolving discrepancies, especially in complex assemblies where such variations are common. It's important to note that this method can also be applied to variations in mass, ensuring consistency across all aspects of assembly documentation.
