Placing a wafer item after a valve that has flanged ends (not wafer) will give incorrect bolt lengths as it adds the length of the valve not the flange thickness in the bolt calculation. To replicate this in the Metric project using mA1-OPM spec 50mm place the following items WNK Flange - WNK Flange - WNK Flange - Spectical Blind - WNK flange - WNK flange - Ball Valve - Spectical Bind - WNK Flange WNK Flange - WNK Flange BOLT Length = 89mm WNK Flange - Spectical Blind - WNK flange BOLT Length = 95.4mm WNK flange - Ball Valve - Spectical Bind - WNK Flange BOLT Length = 274.6mm (Should be 95.4mm) The last calculation has added the valve length not the flange thickness I could not find a fix for this, please point me to the WIKI that fixes this. Thanks Ray
