This is a list of a few known issues which are generally easily resolved and helpful information below to get the best experience from the software.
Please check that your version of Revit is up to date. You may do this in the Revit Menu by clicking on About Autodesk Revit.
Please check if your Revit version has the latest update and patches/fixes from Autodesk. The Autodesk Desktop App is available for this purpose. It will suggest relevant updates for your applications.
It is important that whatever Revit version you are using has the most recent updates from Autodesk so that it will work well with FenestraPro. Your Revit version may be checked by navigating to the Help Menu and scrolling down to the About Revit section. Clicking on this will open a new window where you may view the current version number that is installed.
Please check regularly that any updates released by Autodesk are installed if required.
Access to FenestraPro’s web-service may also be blocked by your company firewall or anti-virus. Please check with your IT Department if this is the case.
Please contact us for assistance in this event at email@example.com and we can send you our online paths to confirm that access is available.
This error message may display if you are launching the application.
In this event, please clear the cache files that are periodically stored on your machine as results are gathered.
This may be done by browsing to the FenestraPro folder on your machine.
This may be found at C:\Users\YOUR USERNAME\AppData\Local\FenestraPro. All files here may be safely deleted as they will be recreated when you launch the application again.
Please then relaunch the application and sign in with your credentials.
With some models, loading elements may be affected by other views being open in the background eg. Plan Views open as well as a default 3D View. In this case, please close other views that are open or tiles views before launching the application.
Periodically, your license token may expire. This may happen over an extended period or if your FenestraPro session is left open in Revit. This is easily resolved by signing out and signing back into the application. When signing in, you may also check the option 'Stay Signed in'. This will prevent the license token from elapsing.
If FenestraPro does not appear to add new entries to Revit's list, Revit may need to restart to update its list. The new Glass Types will then be added and the properties will be applied.
There may also be an issue with access to this file and permissions to edit. During installation, FenestraPro will check that permissions are set correctly to allow the application to update this Revit file. If the Constructions.xml file is subsequently edited manually, substituted by another file eg. with extra materials/construction types, permissions may revert to read only, then updating of this file with new Glass Types will cease to function. This may be resolved by re-installing FenestraPro for Revit. This will restore permissions to edit the file.
Security permissions may be manually set for this file, this is an advanced process and is recommended to be done by those with sufficient expertise. Please contact us if editing permissions are restricted on your machine or if your Revit files are stored in a location other than the C: drive.
If there are multiple entries in Revit’s Constructions.xml list with the same name, Revit will use the entry which is last in the sequence. An entry which has the same name in the Glass Database and is chosen for selection, may have a set of properties which do not match an entry in Revit.
This may occur where there are several entries in Revit for Glazing Types which have the same name eg. ¼” Double Glazing. Revit's internal list may contain an entry with one set of properties, a second entry with another set of properties and a skylight entry with a different set of properties.
Revit invariably will use the last entry that appears in the list sequence which may be the skylight version. An entry chosen in the Glass Database which appears to have the same name, therefore may not map to the correct Revit entry as expected since there are multiple entries with the same name.
Users are therefore advised to check the thermal properties in Edit Type to confirm that the entry has mapped correctly and that these are the properties that they intend to assign. This may be resolved by editing the name in the Constructions.xml file to avoid duplicate names. This is an advanced process and should only be attempted by an experienced Revit user. Editing the file incorrectly may cause errors and prevent the file from being read so caution is advised. Users with expertise in writing syntax and coding should only attempt modifying this file.
It is known that older versions of Internet Explorer (eg. Version 7 and older) and other older browsers may not provide the required links to the online service.
Please use a more up to date browser or another browser type eg. Google Chrome, Mozilla Firefox, Microsoft Edge etc
This may also occur when you are creating a password for your online Account. If possible, use a more up to date browser and make this the default browser before clicking on the invitation email link. Alternatively, you may copy and paste the url from the non-functioning browser into another browser.
When creating a Curtain System, they should be created separately on each orientation and for each wall of the project. If Curtain Systems are placed on several orientations and on several different areas of the model at once, it will be read as one object and separating these out into Facades and Surfaces will not be possible.
Creating multiple curtain systems at once in Revit, provides information to the application for one system with a number of grids. The application will get an average orientation across all grids. This could lead to unexpected orientations and results. It is best therefore, if 'Select Multiple' is not used during Curtain System creation.
Curtain System creation is most compatible when the glazed walls are modeled in separate editing sessions in Revit.
Certain windows themes or personalizing your desktop may conflict with the graphics used in FenestraPro. If this occurs, please try changing the desktop theme to a simpler Microsoft Windows theme to see if this improves display of the application. Please report any issues to us at firstname.lastname@example.org
An error may occur if FenestraPro is used to map glazing properties in the model which has just been modified or deleted. This may occur for example, if the Add Windows or Add Curtain Walls feature is used and then this is reversed (the glazing that was created is then removed/undone). Attempting to apply properties to this glazing in FenestraPro may cause an error since the element no longer exists in the model.
This may also occur if properties have been applied to glazing which is subsequently deleted. This is not an error but simply a referencing issue where model elements are created or removed, and dependent properties need to update. Users are advised to work methodically and allow the application to refresh and update as changes are made. If major changes to the model geometry are to be done, it is best to close FenestraPro, modify the model and open the application when you are ready to analyze again.
If any changes are made to the model geometry, please use the Refresh button on the Dashboard to re-create the Energy Model to keep the results, surfaces and referenced elements current.
If changes are made to the model geometry, Solar Loads will need to be recalculated in the Building Manager to update any modified orientations. By opening the Building Manager, you may notice that an orientation has gone grey and has reverted to zero. The application has identified that modifications have been made and Solar Loads will need to be recalculated.
If the model is changed substantially while FenestraPro is open (glazing is created or deleted or geometry is altered), you may need to go back to the Building Manager to Calculate Solar Loads again. In some cases it may be prudent to close FenestraPro to make the model changes in Revit and then reopen FenestraPro to start afresh.
This may occur after elements which were generated on the model are then deleted and Revit must recreate the Energy Model to update. The Surface has changed while Revit is using the older version of the Energy Model. You may see a message in Revit similar to ‘The Referenced Object is not valid...’. Use the Refresh button on the Dashboard to regenerate the Energy Model.
To Add Windows or Curtain Walls using the tools in the application, the wall selected must be free of any existing glazed elements. The function may not operate if glazing on an adjacent wall is very close to the corner. If possible, temporarily move the glazing back away from the corner. There is also a tolerance value in Settings which may be adjusted an may help when using these tools.
A message may appear if an element in the Revit model has been modified or deleted and the Energy Model has not yet updated. You may need to click this message several times to close it. When the message has closed, please recalculate the Solar Loads again in the Building Manager to bring the application up to date.
This is due to the Energy Analytical Model (EAM) being out of date after the model is modified in Revit. A typical message displayed is ‘The referenced object is not valid, possibly because it has been deleted from the database or its creation was undone’. Attempting to apply a new glass type to tan element that has been deleted may also display an error message such as 'the selected glazing has been updated...'. Highlighting may also fail on the model or the Surface Viewer may not display in the list of Surfaces (Facade Navigator).
Windows or Curtain Walls may have been created or deleted or the geometry changed in some way. In this case, the Surfaces may need to be updated to include the recent changes. Objects may no longer be in the previous location. This may happen if the number of Surfaces have now changed and need to be re-assigned.
The changes may not be updated to the Energy Model or Refresh may not have completed. If major modifications are to be done to the model, it is best to close FenestraPro before you embark on these changes. You may relaunch when the model is ready for analysis once again.
Areas reported are taken from Revit elements, not from the Energy Model which provides a further breakdown of glazed surfaces etc. Please note that where Openings have various materials but only part is glazed, the entire opening area is reported. If you require more detailed areas, please refer to the Revit model itself and glazed families.
These issues are to be addressed in future versions of this tool.
Please close Revit and restart to reset internal references. Open the model again. (Shading Factors needs to have been included in the Building Manager to view shading effects in the Shading Viewer).
If this does not resolve it, it may be necessary to clear previous stored files that are saved in the FenestraPro folder. This may be done in Settings, under the Common tab, use the Clear Cache button and relaunch the application.
When using the Spatial Elements option and launching FenestraPro, a Revit message may display:
This message may display, even though there are Roofs and the Room upper extent appears to reach the Roof element.
If you click OK and continue, FenestraPro will launch but Roof properties will not display in the Performance area.
This may be resolved by closing FenestraPro and going to the Properties palette in Revit. Select the Roof element(s) and check the settings for Upper Limit and Limit Offset. The Upper Limit may need to be set to the Level above the Room base. The Limit Offset may need to be adjusted so that the Room Upper extent touches or extends past the Roof.
Where the Upper Limit is set as the Room base level, this message has been seen to display. A Section View can help to visualize and understand the Room extents in the model
