Naviate MEP + Fabrication: Known Issues

  Product Version Command Description
1 [N] Fabrication 2021-2026 Fabrication Bloom Settings Worksets set in Fabrication Bloom settings are not applied when Blooming from an ITM to an ITM.
2 [N] Fabrication 2021-2026 Hanger Host Elevation Update Command may have unexpected results for Cable Trays.
3 [N] Fabrication 2021-2026 BOM If a Naviate Filter is modified after being set in BOM Options, the BOM Type using that Naviate Filter does not update and it may use the old settings of that Naviate Filter. Fixed in v3.12
4 [N] Fabrication & MEP 2021-2026 Set Slope Values using commas as a decimal may produce unexpected results.
5 [N] Fabrication 2021-2026 Hanger Rod Extension ‘Select Elements’ UI could disappear when selecting a Linked Element. Fixed in v3.12
6 [N] MEP 2021-2026 Copy Monitor Plus Newly copied CM+ RFAs could have an Elevation value referencing Project Base Point, rather than its host’s Level. CM+ Color Toggle may display incorrect colors immediately after Copy.
7 [N] Fabrication 2021-2026 Advanced Renumber When importing a file in ADV Renumber, an unhandled exception could appear if the file is non-JSON format. Fixed in v3.12
8 [N] MEP 2021-2026 Create Circuits Command may unexpectedly cancel if ‘Voltage’ or ‘Number of Poles’ parameters are instance parameters
9 [N] Fabrication 2021-2026 Total Station Points Export Unexpected results may appear when Point coordinates are referenced to Internal Origin. Fixed in 3.12.1
10 [N] MEP 2021-2026 Split and Split with Gap When command is executed near a Fitting instance, the command will error. If Continuous Modeling is enabled, the command will undo any executions in the transaction.
11 [N] Fabrication 2021-2026 Elbow Commands Slope may not be applied to the resulting Ductwork if executed from a Sloped Fabrication Duct. 
12 [N] MEP 2021-2026 Elbow Commands

Elbow commands currently do not support running for multiple non-vertical elbows.

A rotated 'Bloom' Duct could be modeled on Rectangular Duct Fittings if chained from another Naviate Modeling command.

13 [N] MEP 2021-2026 Spool Manager/Advanced Renumber Renumbering a Spool from a 2-digit to 3-digit number may not execute AutoPadding.
14 [N] Fabrication & MEP 2021-2026 Advanced Renumber

If a Naviate Filter is associated to an Advanced Renumber Setting and then renamed, user may need to re-associate that Naviate Filter in Advanced Renumber.

Additionally, renaming a Setting/Sequence could cause duplications in the Setting Columns Assignment window of Sequences.

15 [N] MEP 2021-2026 Reroute Around Command may have unexpected results when executed on multiple straights.
16 [N] Fabrication 2021-2026 Fab Kick 90 Command may experience long load times in large models where a Fitting is connected to a complex Fabrication Service network.
