We receive Model Revision 2 but the file_jt.prt does not get updated.
Use Case in DMU Dept.:======================DAY#1 :- We receive the 3D Model Rev.1 in JT format from CAD Engineers.- let's say 123.jt representing a Block just for this simple example.- we analyze it, then we delete it.
DAY#2 :- We receive the same 3D Model Rev.2 in JT format from CAD Engineers.- let's say 123.jt representing a Cylinder just for this simple example.
- now we take a normal prt containing the original CAD prt of the block, not "derived" from any JT. This is the native part and we rename it to 123_jt.prt (by hoping that xxx_jt.prt is good enough for the Update)- and we copy it into Test directory, where also the Rev.1 123.jt is saved.- in NX12 we File/Open 123.jt and we expect to see a cylinder.- ISSUE : we see a Block, and NX has opened automatically 123_jt.prt. The NX Part has not been updated as we expected.- EXPECTATION : we expect to see the new 3D Model Rev.2 - The Cylinder
This is working as designed, because 123_jt.prt is not a real/correct "derived" part.Therefore the Workflow is not correct.
In order to follow the correct Workflow please use this one :1) DAY#1 : - File/Open 123.jt in NX12 from Test directory- File/Save - (now the correct "derived" part is created and the associativity with 123.jt has been memorized in the 123_jt.prt, created right now inside Test dir.)
2) DAY#2 :- Delete the old 123.jt (Block) from Test directory.- download the new 123.jt (Cylinder) into the Test directory- File/Open 123.jt in NX12 from Test directory- (now you still see a Block)- select Assembly Navigator page- on 123_jt hit MB3/Properties- on the bottom of this Dialog hit on "Update Part File" button- now you see the Cylinder, as requested.- Optionally use File/Save if you wish to maintain/save Model Rev.2 on hard disk.
If you wish to avoid the "Update Part File" Step, but you need an automatic Update, please see this Article :File/Open JT loads wrong Geometry - "derived" part is not automatically updated
