Currently, a multi-slope Roof modeled as a single element reports only one row in Schedules — the total area of the element. There is no way to list each individual face (sub-geometry) separately with its own area and slope value. This forces engineers to either: - Split every roof into multiple separate elements (breaking the model intent), or - Measure and annotate each face manually (static, error-prone). Proposed solution: Allow Roof Schedules to decompose a single Roof element into its individual sub-faces, exposing per-face parameters as separate rows: - Face Area (actual sloped area and/or projected area, in m² or ft²) - Slope (as %, degrees, or rise:run — user-selectable) - Face orientation (optional) This would enable direct hydraulic sizing of stormwater conductors from a Schedule, without any workaround, fully within BIM parametric workflows. Any geometry change in the model would automatically update the table. This feature is particularly relevant for MEP/plumbing engineers who must calculate roof drainage per local standards (e.g. ABNT NBR 10844, EN 12056-3), where each roof face must be individually sized.

The Problem In hydrosanitary MEP projects, vertical pipe risers are one of the most critical and repetitive elements to document. Currently, creating a riser in Revit requires multiple disconnected steps: manually drawing a vertical pipe between levels, separately placing an annotation tag, manually typing the riser ID (e.g. AF-02, AQ-01), and then verifying that the tag style matches the system type — all repeated for every riser in the project. This fragmented workflow is slow, error-prone, and inconsistent across team members. There is no built-in way to enforce a naming convention, automatically increment riser IDs, or ensure every riser is properly tagged on placement.   The Proposed Solution A dedicated "Vertical Pipe Riser" tool in the Mechanical/Plumbing tab, similar in concept to the Column tool in the Structural tab, with the following behaviour: 1. "System type selection" — the user selects the piping system (cold water, hot water, sanitary, stormwater, supply, etc.) before placing. The tool inherits the correct pipe type and system classification automatically. 2. "Level span" — the user defines the bottom and top levels directly in the tool dialog, so the pipe is created at the correct vertical extent in a single click on the floor plan. 3. "Automatic riser ID" — each riser is assigned an ID following a configurable pattern (e.g. CW-01, CW02, HW-01) stored as a shared instance parameter, with auto-increment after each placement. 4. "Annotation on placement" — an identification tag (balloon annotation) is placed automatically at the point of insertion, using the tag family associated with the piping system, displaying the riser ID and nominal diameter. 5. "Riser schedule" — a built-in filtered schedule shows all risers in the current view or project, grouped by system, with their IDs, diameters, and level extents — enabling fast quality control.   Why This Matters Riser documentation is mandatory in hydrosanitary and fire suppression permit submissions in many countries. Errors in riser identification (wrong ID, missing tag, inconsistent naming) are among the most common drawing review rejections. A dedicated tool would eliminate these issues at the source, saving hours per project and improving drawing quality directly. This would be especially impactful for MEP engineers working on multi-story residential and commercial buildings, where dozens of risers across multiple systems must be coordinated and annotated consistently.

This issue use to work with previous Revit before 2026.  Would like to have the implementation of using nested families couplings to work with taps.  When connecting the taps with a nested coupling, Revit would throw out an error.  This does not happen prior to Revit 2026 and would like to have the feature be implemented back in.  Help article of Revit 2026 stated that this is fix, due to the instability of Revit crashing, but would be helpful for MEP designer to have this feature be put back in.

Double containment piping systems are widely used in industrial, process, and water/wastewater projects for safety and environmental protection. Currently, Revit does not provide native support for such systems, requiring users to create complex workarounds. We recommend introducing native double containment pipe and fitting functionality with the following: Parametric control for inner (carrier) and outer (containment) pipes Automatic alignment and coordination between both systems Standard fittings compatible with double containment logic Accurate scheduling and tagging capabilities Benefits: Improved modeling efficiency Reduced manual work and errors Better support for industrial and infrastructure projects This feature will greatly enhance Revit’s capability for process and plant design workflows.

In some buildings, there are rooms within rooms. This occurs, for example, with permanently installed containers inside a hall or in server rooms with hot and cold zones. Currently, MEP spaces can only be determined based on their floor area up to an upper boundary. If there is an additional smaller and shallower space within a MEP space, the air volume above and, if applicable, below this inner space is not assigned to the MEP space. One possible solution would be to calculate the MEP space as a whole and treat the smaller / shallower internal space as an independent MEP space. Its technical values (volume, enclosure area, etc.) would then be taken into account within the larger MEP space. The representation of hot and cold zones in server rooms is intended to illustrate this issue. Show More

Many Manufactures use this parameter as it was intended to indicate if the fitting with the specified dimentions exist in their catalogue or not. It's stupid that they then have to add an aditional custom shared parameter to replicate the same behaviour (or the oposite) just so we can schedule and/or filter...  We end up with dozens of equal shared parameters when we have a great one already in the program. Please revise this so we and the manufactures can make better and ligher families. PS: while you are at it, expose all other still missing parameters too - there is a bunch of wish list ideas just like this one for many other OOTB parameters. Show More

how come is it possible that user cannot control the visibility of the Tags from attached model (in grey color) in the meaning : "what is below and what is on top" ?  (even i have attached model as an "underlay") design for sheets in final state looks very messy though    please call for action to do with this silly issue something Show More

Instead of a giant pick window then filtering out what I want to be selected, just the same concept in reverse.   If I am working in a lighting plan and need to move or modify a lot of switches, a "pre-filter" so that my clicks and mouse drags to not grab anything but switches.    This exists for links/underlay/pinned elements, but would be nice if you could make it work for any category.

Hello everyone, I wanted to bring to your attention an important matter regarding our clients' increasing BIM maturity and their rising expectations for our model deliverables.   One of the most frequently requested BIM requirements is the Uniformat Classification in our Revit families.   Currently, this parameter is set as a “type” parameter, which has led to several issues. Changing this to an “instance” based parameter would effectively resolve many of these concerns.   Issues for the mechanical discipline Case of Pipes, pipe fittings, pipe accessories, pipe insulation, flex pipes + equivalent Duct: In mechanical design, we use a Pipe type (and Duct type) that represents a material (for example, black steel with threaded fittings), which is then used across different Uniformat categories (heating, cooling, plumbing, etc.). Since the same material is used in different Uniformat categories and because the Assembly Code parameter is set at the Type level, we are forced to duplicate pipe types, pipe fittings, pipe accessories (and their Duct equivalents) solely to differentiate Uniformat codes. Duplicating these elements creates challenges for model quality management. With the Assembly Code parameter set at the Instance level, we would not need to duplicate families for Uniformat purposes. These concerns occur in other disciplines as well. Show More

I think it would be handy to be able to see what filter is affecting any object in the plan view either for sheets or coordination (Pipe, tray or builderswork hole) by selecting the item and seeing within the properties tab the filter that is affecting it.  Show More

  Dear Autodesk Team, I am an MEP BIM Modeler working with Autodesk Revit for plumbing, drainage, HVAC, and fire fighting systems. I would like to suggest a feature that could significantly improve system understanding and BIM presentations. Idea: MEP Flow Visualization Currently in Revit, we can model complete MEP systems such as drainage pipes, water supply lines, HVAC ducts, and fire fighting networks. However, it would be very useful if Revit could also visualize the actual flow inside these systems. For example: 1. Drainage System Water flow visualization inside pipes according to the pipe slope. 2. Water Supply System Animated water flow direction inside supply pipes to help understand system behavior. 3. HVAC Duct System Airflow visualization inside ducts using moving arrows or particles. 4. Fire Fighting System Sprinkler water spray or water flow visualization for fire fighting systems. Integration with Navisworks In many BIM workflows, MEP models created in Autodesk Revit are exported to Autodesk Navisworks for coordination, review, and presentations. It would be very beneficial if this MEP Flow Visualization could also work after exporting the model to Navisworks. This would allow teams to: Visualize water flow in drainage systems Show airflow direction in HVAC ducts Demonstrate fire fighting water flow and sprinkler operation Use flow animations for client presentations and training This feature could also work together with Navisworks Timeliner to simulate system flow over time. Benefits Better understanding of MEP systems Improved BIM presentations and coordination meetings Easier training for new engineers and BIM modelers More interactive and intelligent BIM models This feature would help engineers, BIM professionals, and clients better understand how building systems actually function inside the model. Thank you for continuously improving Autodesk tools. Best regards MEP BIM Modeler Show More

Within our MEP office, it seems one of the primary challenges we've had with the integration of Revit is the lack of electrical functionality when it comes to project phasing. Various components of this have been suggested over the years, but it seems like the ask could be simplified as follows:    Provide project phasing for electrical circuitry. In the real world, circuits existing in a place and time like all other model geometry, so it doesn't make sense that they are handled like annotations/analytical calculations that exist only in the scope of work.  Allow for use of phase filters on electrical panel schedules.  This allows for a designer to display and existing and revised condition. This is typically displayed on every project that involves modifying the loads associated with a panel.  I am aware that there are work arounds using Excel or Drafting views, but this is definitely a hang up every time we train a new electrical drafter/designer.  Show More
