• The calculation of Scrap Part Credit does not account for parts scrapped due to processes that occur before the designated “utilization process” in the routin. For some routings, this issue can result in a calculated Scrap Part Credit value that is just slightly less than the value that you could otherwise achieve.

• The Continuous Extrusion process which is used for extruding powder metal or solid feedstock into continuous rods is not yet supported in the aPriori baseline cost model.

• For bent parts made from custom extrusions, aPriori may fail to correctly extract the extrusion cross-section profile and/or fail to recognize bent geometry as Bend GCDs. This can occur when the CAD model contains incorrectly modeled geometry, such as having a bend which is not tangent to adjacent surfaces of the extrusion or having a cross-section which is not oriented normal to the trajectory of the bend along the entire length of the bend.

• Some bent extrusion parts may not cost completely in the initial release, due to a lack of feasible bending processes in the aPriori baseline cost model. aPriori intends to provide additional Bending processes in a near-future release in order to accommodate such parts.

• aPriori assumes the use of a single Router tool to machine each Cutout GCD. In some cases, aPriori may choose a smaller or larger tool than would be used in practice to machine a Cutout, leading to incorrect cycle time and cost estimates. For example, if the Cutout includes some small-radius fillet surfaces, this could drive aPriori to choose a small-diameter tool when in practice the majority of the Cutout would be machined with a much larger tool.

• If an extrusion part contains a MultiStepHole GCD, the SimpleHole GCDs which comprise it will fail to cost in aP 2019 R2. This issue is expected to be addressed in aP 2019 R2 SP1.

• If a part’s cross-section contains a curve which is not an arc (e.g., a spline), aPriori will not recognize the part as a custom extrusion.

• It is possible to manually select a routing which includes a 3 Axis Mill or 5 Axis Mill for secondary machining of extrusions, however the Cutout GCDs will fail to cost.

• For Composite parts, Material utilization is determined by assuming an average per material, rather than on a per-ply or per-part basis

• For Composite parts, Cores are assumed to be bought in a pre-cut state. The cost for core materials in the database represent the area-based cost of the given thickness of the core material. The user has the ability to override this assumption and specify the cost of the core piece in the GCD properties window.

• In the Composites process group, if holes are not modelled, no holes can be detected and therefore the costs associated with hole-making are not included in the aPriori estimate.

• Co-cured parts such as structural integrated panels are not supported in the initial release of the Composites cost model.

• The new Manual Paint process is located as a peer of the Paint node, at the end of the Surface Treatment routing choices. In a near future-release, it will be moved to appear under the Paint node, so that it is grouped logically with other Paint processes such as Wet Coat Line and Powder Coat Cart and easier to find and select.

• When upgrading to aPriori 2019 R2 from a previous release of aPriori, a user’s preference setting for Exchange Rate Version is not preserved if it was set to any value other than Default.

• When you upgrade to a new release of aPriori Professoinal, if your aPriori password was saved as clear text in the aPriori database for the prior release, the aPriori login generates an error when you try to log in to the new release.
