Title: Alternative Drop-Cutter Algorithm with Angular Clamping, Bridging, and Safe Pivot-on-Spot for 5-Axis Finishing with End Mills   Description: Currently, when using End Mills or Toroidal tools under a specific lead/lean angle relative to the surface normal on complex 3D surfaces, Autodesk PowerMill’s standard gouge checking algorithm often leads to erratic tool axis behavior. The system continuously micro-adjusts the tilt or forces excessive lifting to maintain perfect mathematical contact, which ruins machine dynamics and surface finish. We propose implementing an Alternative / Simplified 5-Axis Drive Algorithm designed specifically for practical mold/die machining, based on the following logic:     1. Vector-Driven Drop-Cutter Approach: The system should orient the tool according to the user-defined lead/lean angle relative to the surface normal at the target point, and then drop the tool along this specific vector until the FIRST point of contact occurs anywhere on the tool geometry (bottom, corner radius, or side).   2. Safe Material Remainder Concept: We understand that the center of the tool might "hover" over depressions, leaving unmachined material. In practical mold-making, this is acceptable, as remaining stock will be removed by subsequent rest-machining operations with smaller tools. Preventing gouges and maintaining smooth machine movement is the primary goal here.   3. Angular Clamping (Controlled Tilting Limits): If the initial drop causes a heel/rear-edge collision, the software should allow the user to specify a strict angular range (e.g., between 5° and 15°). The system can dynamically tilt the tool only within these specific boundaries to clear the heel.   4. Non-Plunging Linear Interpolation ("Bridging"): If a collision cannot be resolved within the defined angular limits, the algorithm must NOT force the tool to plunge into the cavity or stutter. Instead, it must bridge the gap by locking the tool axis orientation and moving in a straight linear interpolation line to the next valid point.   5. Safe Pivot-on-Spot & Temporary Bridge Part: When the tool reaches the next valid point where the rear-edge collision is no longer present, it needs to pivot/rotate back to its standard lead/lean orientation. To prevent the rear edge of the cutter from plunging into the stock left under the bridge during this rotation, the software must treat the bridge line as a temporary part geometry. The tool must perform a controlled pivot-on-spot, ensuring that neither the bottom nor the rear edge violates this temporary "bridge" boundary.     Benefit: This alternative algorithm would provide an incredibly smooth, fluid 5-axis toolpath for flat and toroidal cutters on wavy, complex surfaces. It eliminates frantic tool axis oscillations, protects the machine's CNC drives, extends tool life, and delivers a predictable surface finish, leaving cleanly defined rest-material for subsequent operations.

Make it possible to either automatically export a DXF file of the nested table after processing or use the Nest DXF Export feature in Scripting. In our workflow it is easier to have the machine use the DXF file as it can make adjustments according to the sheet orientation on the table. It can not do that with the G code. Show More

Howdy everyone. I found and fixed a bug in MEP Content Editor Sync that required I run the tool as administrator in order to view available configurations. This isn't much of a problem for me as I have an admin account, but no one else on my team does.   After a little snooping in the logs I discovered that the problem is an effect of the following:   %ProgramFiles%\Autodesk\MEP Content Editor Sync\resources\app\main.js calls reg.exe to get MachineGuid from HKLM:\\SOFTWARE\Microsoft\Cryptography The IT Security team at my org has disabled registry editing by non-admin users; Any calls to reg.exe are guaranteed to fail As a fan of PowerShell I know that I'm able to read reg keys and values from a standard account using the command Get-ItemProperty. I made a few changes to main.js and now MEPCE Sync is working as expected from a standard user account (no admin privileges required).   Note: main.js is minified out of the box - I formatted the document with Prettier in order to debug. I've included line numbers as comments after formatting, but your mileage may vary. A quick search for reg.exe should help you locate the relevant code in your files.   main.js (Before) case "win32": // ln: 17533 return e .toString() .split("REG_SZ")[1] .replace(/\r+|\n+|\s+/gi, "") .toLowerCase(); // ... win32: { // ln: 17577 native: "%windir%\\System32", mixed: "%windir%\\sysnative\\cmd.exe /c %windir%\\System32", }[i()] + "\\REG.exe QUERY HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Cryptography /v MachineGuid",   main.js (After) // The case statement in this section is expecting 'REG_SZ' to be present // in the value returned in the later section. My patch doesn't include // that text in its return value, so we have to account for that here. case "win32": { // ln: 17533 var p = e.toString().split("REG_SZ"); return (p.length > 1 ? p[1] : p[0]) .replace(/\r+|\n+|\s+/gi, "") .toLowerCase(); } // ... win32: { // ln: 17577 native: "powershell.exe -NoProfile -Command", mixed: "%windir%\\sysnative\\cmd.exe /c powershell.exe -NoProfile -Command", }[i()] + " \"(Get-ItemProperty -Path 'HKLM:\\SOFTWARE\\Microsoft\\Cryptography' -Name MachineGuid).MachineGuid\"",   I hope this helps someone else as much as it has helped me! Maybe someone from Autodesk can take a look at integrating this as a fallback in the next version of MEP Content Editor Sync.   My apologies if this is not the correct board for this sort of topic.

I would like to propose the idea of adding a setting to our connectors which would govern if a connector is displayed in the dropdown selectors of the interface, dependent on the software application being used.   Our CAM operator has added many oddball connectors to our database over the years to fill orders that the field has sent into the shop. There are a lot of flange widths, hems, connectors with extensions, connectors with step-ins, etc. The shop needs these connectors in the system and I do not want to remove them.  Our detailers have to sift through a massive list of connectors to find what they want. They do not need to look through all of these connectors. It slows them down and I certainly do not want them to choose any of them.   I would like to be able to set a connector so that it does not show in the list for a Revit user, or an ESTmep user, while I want them all to be shown to the CAMduct user. There are even connectors we have set on Bought Out parts that I would love to be able to hide from the CAMduct user when he uses his keyboard to quickly cycle between connectors when he is inputting fittings.   Show More

Issue: In Fabrication CADmep 2026, the LFILL (Line Fill) command intermittently applies insulation to newly created parts even when the active service has no insulation specification assigned. This occurs despite the service database being confirmed clean and does not affect parts placed manually or via other routing methods. The issue appears isolated to LFILL behavior and is reproducible within the same session. Observations include: LFILL-created parts showing insulation when Service Insulation Spec = None The issue occurring after switching from an insulated service to a non-insulated service Insulation persisting at the part-instance level even after reapplying the service Manual part placement not exhibiting this behavior Insulation only clearing if manually removed or if the service insulation is temporarily toggled on and off This means every pipe that incorrectly assign insulation requires manual cleanup via Item Properties.   To reproduce this issue: Open CADmep Draw pipe with a service that has insulation assigned to it Switch to a non-insulated service Run LFILL Insulation appears on non-insulated service   After discussing possible causes/workarounds with ChatGPT, it told me this:   (Not sure if it helps, or is even accurate)   - LFILL appears to reuse previously initialized part data or cached part state and does not fully re-evaluate or clear insulation metadata based on the active service at the time of part creation.   Show More

I try to use CID 1110 for anything that can't be accomplished with any other pattern.  But there are limitations to this CID.  Could you enhance this pattern by doing the following: When initially using the command MAKEPAT and entering 1110 for the CID, give us a blank canvas to start building our element instead of already having a box. Allow the ability to add a polygon shape and set the number of sides to that polygon.  Or maybe just enhance the box shape to be able to set the number of sides instead of just 4. Instead of adjusting the radius for all the corners of a box to be half the width, height, and/or depth, allow the ability to add a cylinder (something round without a connector) to eliminate the need to input so many additional values to make something round. Allow adding a loft shape.  This loft shape could be like a square to round, a round to round. a polygon to round, etc. Allow adding a shape that bends.  As an example a 90 degree elbow where you can assign a diameter, bend angle, and center to end length dimensions. Allow the removal of a shape or connector. Allow changing the parent ID. Add an X, Y, and Z rotation to any shape or connector that is added. Allow positive and negative value offsets in the Z direction to any shape or connector that is added (X and Y are already available). If the added element is Round and the Circular Diameter Type is set to Nominal, then adjust the outside diameter to match the outside diameter for the corresponding material table. Allow chamfering and filleting of corners. Allow a thickness to be added to a shape with an opening.  As an example, if I create a cylinder that is open on both ends, I may want to add a wall thickness to represent the inside diameter of a pipe. Allow stretching unlocked length values within AutoCAD or Revit. Eliminate the insertion point snap/grip so it does not show up in AutoCAD or Revit.  Only show the snaps/grips for the connectors. Allow this CID to be cut into a run of pipe/duct or cut around the pipe/duct without breaking the straight run.  If it is cut around an element in Revit, make it hosted to that element so it moves with its host.

CID 916 would be a great pattern to use for p-traps that are tapped for a trap primer.  But CID 916 doesn't allow the branch size to be adjusted independently of the inlet and outlet of the p-trap.  Could you give us the ability to add a different size for the branch on this pattern? Show More

The drainage standard AS/NZS 3500:2 4.9.1 (2021) has been updated and now requires a 15-degree incline on the branch of the 45-degree junction when connecting 100mm drains. We have been achieving this by rotating the junction and then using a 15-degree bend to correct the drainage grade back to the required 1:60 after the incline, which works but is time consuming.  A new fitting has been released that incorporates the 15 Deg offset into a single fitting, however, the closest I can get to a workable CID is Pattern  2938, however the Angle adjustment controls both the branch angle and the offset angle. If the offset angle could be altered independently, this would allow the correct adjustment with the rotation valve.  I would like to see a pattern like 2938 that allows for the branch to be rotated around the body so that when inserting the fitting it does not require constant rotation after insertion, and the second angle is independent of the branch angle, moreover, the pattern has angle tolerance to allow for sloped connections. Or if anyone has any suggestions on other patterns I should try.      Show More

We could really use a script when straight is added or unequal as a flag/selection on the CAD side. We are running into issues on our install drawings not showing rectangular or round fittings when we added straight to Connector 1 or Connector 2. Example: elbows. The script would just need to select them at a minimal for identification. Show More

We are a HVAC manufacturer working in both low integrity and high integrity specifications. We have found that the current straight types do not work for high integrity items in some cases and would benefit from a new option. We would require "2xU" to accurately position branches, access doors and other ancillary parts on our welded straights. None of the existing patterns work because 1 Part straight is too large for most parts and is not possible to fold, 2xL offsets everything 90 degrees, 4xL-M-F doubles the amount of welds required which is unacceptable to our quality requirements, 1xU,1xL puts all of the weld strain on one side of the item. We would like to apply the seam in the middle of the sides, however if there was an option to not have seams on the bottom of the duct, this would be ideal because of quality requirements and stops any water pooling on the weld/seam Item CID 1 and 35 would be required for this, 866 would not be necessary as we only decoil folded 2xL items Please Kudos this request if this would also benefit your own fabrication facilities Show More

The labels should be placed on burned panels facing the same orientation as the Graphical CNC view. So, after the fitting is assembled all the labels are facing the same direction.  For example, C1 is always facing the bottom.   This used to be the case, but after years of updates CAM lost this function.  Show More

Fabrication is part of Revit as of 2015 now. However, we are still missing the use of sub-assembly's (as defined in CAD) in Revit. Yes, we can have hybrid models with MEP and fabrication parts, yes we can create an assembly in Revit. But we still can't use the sub-assembly's we made in fabrication Cad-mep (combined parts).

We have a number of items on which we have locked length parameters (calculated!). Locking parameters can only be done by editing the .itm file (not in a placed part).  Works as intended in Cad, no issues there. However, if the part is used in Revit, it allows stretching (which in itself is fine), but instead of adding new parts according routing specs (like it does in Cad), stretching is overriding the LOCKED parameter and changes the length (which still is greyed out by the way, so manual change is not possible) removing the calculation. Ofcourse, as Autodesk usually does, they call it by design (they never have a bug). Locked parameters should be respected at all times, they are locked for a reason. If we want them to be allowed to change, we do not lock them. So here's the idea (as Autodesk calls for an enhancement idea instead of bug solving): Respect locked parameters (as you do in CAD)! Attached the movies and pictures that have also been submitted to autodesk as an issue. Show More

In unserer Firma häufen sich die Anfragen, ob es möglich ist, bei Armaturen mit Handhebeln (zum Beispiel CID868) den entsprechenden Bedienbereich des Hebels grafisch darzustellen. Wäre es möglich solch eine Funktion in die entsprechenden CIDs zu implementieren? Die Darstellung eines Bedienbereichs ist notwendig, um Kollisionen mit anderen Rohrleitungen oder Gebäudeteilen ausschließen zu können - eine Funktion, welche direkt in der CID gegeben wäre, würde uns viel Arbeit ersparen und die Produktivität steigern.   (Zum Beispiel eine Yes/No-Funktion in den Options einer entsprechenden CID)         Show More
