You can try this App for free here: https://bit.ly/2IQWR0G Or visit the full App page for pricing information: https://bit.ly/2skgckT You can watch a free webinar on how to take control over your MEP openings in Revit here: https://stabiplan.wistia.com/medias/1slf2a062o To create an opening in any part of the building, you can simply select the desired MEP elements and their corresponding structural elements (e.g. walls). The openings will then be automatically created in the places where they intersect. You can also manually place openings, either non-hosted or face-based. It’s also very easy to edit the dimensions of an opening such as shape, orientation, width or height. A third way to create openings with the Stabiplan Openings for MEP App is by using the Interference Check functionality in Revit.
