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

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.

I would like to see Autodesk actually make some changes that users are requesting via the Autodesk Idea Station - specifically for Fabrication products - whether in AutoCAD or Revit.  Isn't that what the idea station that Autodesk asks us to use is for?   Here are some statistics from the Fabrication Idea Station since the first post was added to this forum back in 2013: 527 total ideas have been posted 474 of those are "gathering support" 35 of those have been implemented 15 of those are slated for "future consideration" 3 of those are archived So since 2013, only 35 ideas out of the 527 have been implemented.  And what is even worse is only ONE idea has been implemented since 2016.  I believe that is around the time that Autodesk thought they didn't need the services of Andy Robins and his team any more.   So let's look at the number of votes that it takes to get something implemented.  Evidently, there are TWO ideas that were implemented with a grand total of 0 votes.  One would think that not a lot of people want that feature to be included.  Yet it was implemented anyway.  However, there are ideas out there with way more votes that are still "gathering support".  One of those ideas has 95 votes! I guess that is not a feature that many people want?   In conclusion, I have to ask - "what do I think the voting actually does for the product that we depend so heavily on?"  In my opinion - nothing.  I would also ask - "what does the idea station actually do for the product that we depend so heavily on?"  In my opinion - nothing.  I believe we have a product that Autodesk feels is perfect and there is no room for improvement - even though there are a lot of good ideas that people are suggesting.   I apologize for my frustration and this rant, but we continue to try to make the product better (especially in Revit), but it falls on deaf ears.  We need hangers to be more robust in Revit.  We need them to work vertically as well as horizontal.  We need trapeze hangers to have the ability to have more than just single strut as a bearer.  We need hangers to wrap around either pipe or insulation depending on what type of hanger it is.  We need sleeves to wrap around the outside of insulation.  We need sleeves to upsize.  We need sleeves to stretch.  We need hanger information visible in Revit.  We need a way of colorizing our services in Revit without using filters (which Autodesk has stated slows down the modeling process).  We need reloading the configuration to not break all of our content.  We need reloading the configuration to be faster.  We need to be able to modify the database from within Revit as opposed to going over to AutoCAD.  We need more parameters available in Revit for certain things.  We need a million other ideas that people are asking for.  I just ask that Autodesk actually listen to its users that spend thousands and thousands of dollars for software that it depends very heavily on.  Hopefully I get a lot of "votes" for this and it gets "implemented".......but I'm not going to hold my breath.   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

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

It would be nice if Autodesk would make it standard that when converting Pattern 928 to Pattern 1175 all item properties are read from the 928 and applied to the 1175 and then make it add all common and product listed item properties to a model list of 1175's when you create a model list including diameters as well. As it stands now the process is almost laughable. For each size of Model item you need to use the Convert3dmodel command which will give you a pattern 928 use the connector block to identify the connector shape and size.  Set all the item properties and connectors          Right Click in the white space of the folder where your 928's are and select the new 3d model item command to turn each of the 928's into 1175's.       Once you have all the sizes of the 1175 built make sure all the item properties and connectors are what you want with those by repeating step 2 again, they will default to ductwork and also some bizarre materials etc. I don't know why they don't inherit the properties of the 928..... I think I'll write a ticket on that because this is a tedious process. In the folder where the 1175's are right click and create a new 3d Model list of the 1175's, use Ctrl to select multiples once you have browsed to the folder.   Once all are selected and you hit open you will once again get to repeat setting all the properties in step 2, have fun with that. After setting the item properties you need to open the product list and add and define the Diameter #1, and Diameter #2 Sizes.     You now have a Model listed part, you can add fields to the product List along with any Custom data you may have in your database.   Show More

It would be great to have the option to toggle your snap to connect to the 'connection' of a piece of fabrication content.   Like so: Show More

As of now the seam for the round collar is applied from the pressure class. Sometimes we need to override that seam. It would be nice to override that seam on the connectors tab. And we would need the ability to change it and lock it via scripting.       Show More

If a connector is "Locked" on an ITM, it should NOT be allowed to be changed in Revit.    In what world would you ever change the connector or a welded elbow to a different connector?   Can't do it in EST/CAD/CAM without being an Admin, why Revit allow this is beyond me.  Show More

Need 2875 to be able to be stretched and work with "optimize lengths".   Make a new pattern if needed but saddles of a fixed length require an added weld typically. If someone's laze and doesn't manually calculate and adjust the branch length, it's going to be a minimum $100 bill each time in labor.    Think of the waste this creates.  Show More

In Fabrication CADmep, can we have section box like Revit? Show More

It would be great is when you define the Rise and Fall Symbols in Fabrication. They behaved as described by Autodesk.  https://knowledge.autodesk.com/support/revit/learn-explore/caas/CloudHelp/cloudhelp/2019/ENU/Revit-Model/files/GUID-7DD57A79-E578-4F75-B40D-D2404B95E4BC-htm.html See Case ID: 17976601 An Even Better Idea would be to be able to use the Symbols available In Revit for System Families (Duct,Pipe,etc) Show More

SMACNA has updated their oval specifications. The do not go by LS/SS but by flat span. It would be nice to see this and to see stiffeners for oval added.  Round needs to be able to have stiffeners as well.    While it would be nice, I don't even care about visual representation - I just want it to be reportable so the shop knows how to build it without having to reference a SMACNA chart. This is pretty important for fabrication and shouldn't be ignored any longer. Show More

In Fabrication Cad MEP software we are unable to slicing any pipe in front elevation. Is there any possibility to do so? Show More

It would be very helpful to have Fabrication Hanger Patterns supported In Revit for vertical piping. As it is now, only the Slide Options Type of pattern 838 is supported in Revit on Vertical Pipe. The geometry of this pattern is not correct for many things this pattern can be used for, hence all the other Options Types that work in CADmep, the vertical pipe needs support just as horizontal pipe does. Some things you could use this pattern for would include sleeves and water stop rings as well and the intended use as a pipe support.   Show More

I'd like to have the ability to drive/change the Support Rod Specifications per instance of support in a similar way we can override the rod diameter. The rod dia changes depending on the material of the pipe being supported and we can only have 1 Support Rod Specification per Fabrication hanger. Instead of having multiple hangers in the library just because of the Support Rod Specifications. Id also like to be able to set this via the API.  Show More

If custom data carried over from pipe to hangers and was accessible for schedules it would be helpful. We use custom data fields to calculate BOP, we then place a hanger schedule on the hanger drawing with BOP associated with each hanger. This way the hanger elevation can be set, then the insulator can let the hangers down when applying insulation.   Show More

It would be an absolute game changer for our business and save countless hours of drawing work if the process of converting Revit services to Fabrication CADmep could work how it was supposed to. All my attempts so far to convert Revit items to Fabrication items have ended up with errors stopping the process working how it should. My process at the moment is to export the design line from Revit and use the processrun command in CADmep to import the items, but this still leaves a lot of work afterwards as the mapping process never ties in completely.   Could somebody point me towards a guide on how to use our Fabrication database/specification to convert Revit items to Fabrication items within Revit so that it could just be exported as a maj file into Fabrication CADmep?
