Revit integration

Make sure you have the things listed below before starting:

• Autodesk Revit 2016, 2017, 2018, 2019, 2020 or 2021 version installed (please note that Revit LT does not support any plugins, accepted versions are also listed in the Revit Store)
• One Click LCA account and license with Business features to be able to import data
• One Click LCA account and license with Expert features to be able to get results back into Revit

IMPORTANT - Updated Revit v3.0.1 BETA plugin available - 23.03.2021

The new plugin introduces multiple new features and improvements. This new plugin version is available for Revit versions 2018, 2019, 2020 and 2021.

Users are strongly recommended to install the latest BETA version (updated on 23.03.2021) and then the final version of the plugin when it becomes available.

Most significant updates:

• The plugin is dock-able and allows users to edit Revit objects while the plugin is open
• Users can choose whether to split objects into materials or keep them as whole objects (eg external walls) and map them directly to constructions or appropriate EPD – Ideal solution for less detailed and concept phase models
• Default units are automatically adjusted for each building part to help users to find mappings more easily and have more accurate calculations (eg wall layers are exported in area, railings in length, doors in pieces)
• Walls are separated to Exterior / Internal / Retaining etc based on function.
• Family and Type are demonstrated and used by default for the grouping of materials
• Project benchmarks and a new graph are enabled
• Fixes in exporting quantities of mullions, reinforcement and railings
• Overall improvements in performance
• Multiple smaller improvements and fixes

Known limitations:

• An error might occur if a user uses “Find matching rows” and “Isolate materials” features quickly for many materials.
• Additional parameters to be sent to cloud, If a user selects an additional Revit parameter to be sent to the cloud (in the plugin settings), the object / material grouping in the plugin and in the export will not be affected by this parameter. This means that theoretically in some cases, the exported values for some of these parameters might not be representative for all the elements in the group. Additionally, if an object is grouped and the user selects to export a material parameter, exported value might not be representative for the whole object except if it is a single material or if the parameter value applies for all materials.
• Linked Models, the ability to continue with linked models is currently not fully working. 
• Removing previously set mappings in the plugin, please use 'right click' and 'remove mappings' to remove earlier selected mappings. Directly overwriting the mappings currently does not always lead to the mapping being overwritten. If the previous mapping is removed first, it will always work.

How do you set up the Revit Integration?

Where can I download it?

• You can download the plugin from the Revit store. In the store search for 'One Click LCA' and follow the steps for downloading the plugin.
• You can also download it directly from One Click LCA either as a zip.file or a exe file. If you download it from this page you will need to unzip it first. The plugin is digitally signed by One Click LCA, however, your operating system may ask you to confirm if you wish to proceed with the installation. In such a case, choose Allow / Yes, as applicable.
• For Revit 2016 and 2017 download: One Click LCA Setup Revit 2.1
• For Revit 2018, 2019 and 2020 download: One Click LCA Setup Revit 2.2 or One Click LCA Setup Revit 3.0.1 BETA
• For Revit 2021 download: One Click LCA Setup Revit 3.0.1 BETA

How do I install it?

The plugin installs seamlessly without options. Download Revit plug-in from the Revit store or from the attachments at the bottom of the page. Unzip it and install it. 

How to use the Revit Integration

Watch our tutorial video of the tool basic functionalities and test the web interface to explore how the tool works before working in the plug-in and exporting the model to the web-interface.

• Step 1: Open your project on Revit

To be able to isolate objects in the Revit model using One Click LCA Add-in, please make sure that you are in 3D view. The view can be selected by navigating to View tab and pressing on “3D view” as seen in the screenshot.

• Step 2: Click “LCA in Cloud” or “LCA in Revit”.

“LCA in Cloud”: Exports quantities directly with default settings.

“LCA in Revit”: Allows editing plugin settings and starting your work inside Revit before exporting, or to work purely inside Revit.

• Step 3: If chosen “LCA in Revit”, start by reviewing settings.

In this tab, you can select Scope, define used and exported Revit parameters, and most importantly decide if you wish to split objects (families) into materials or not. For less detailed model, It is strongly suggested that you select to not split the objects and instead use the whole objects and their area and map them to constructions or EPDs that represent composite products (eg external walls or slabs)

• Step 4: Review and adjust Model and Categories tabs 

In the Model tab, you can define the phases and linked models that shall be accounted for in the assessment. The current phase is selected by default, and the selection allows only one phase at a time to avoid duplicate materials exporting. If you use a linked model, please make sure it is defined which model is chosen, select or de-select models if needed.

In the Categories tab, you can further adjust for each individual object whether it shall be included in the assessment or not, if it shall be broken down to materials or kept as composite object and last, what shall be the default units for each building part or object.

• Step 5: Review materials and start mapping them in the Materials tab.

To generate automated mappings inside the plugin (Expert feature), users need to first log-in (at the Login tab) and then navigate to the Results tab.

Mapping can be also done in the web interface, after the export.

The updated material list and most updated choices for mappings in the plugin, can be exported at any time by clicking “LCA in Cloud” button inside the plugin.

Remember that you can use the “Isolate Materials” feature to understand which Revit element is each material row referring to.

Show “LCA profile” feature enables you to see the details of the selected environmental profile (need to be logged in).

Please mind that in online interface some mappings might change depending the tool that you select to import the data to, and the allowed data for that specific tool.

• Step 6: Generate results

See Results and Graphics to analyze your design carbon impacts.

• Step 7: Export your model data

Click 'Run LCA' to export your model to One Click LCA web-interface.

• Step 8: Follow general import guidance
