The Influence of Revit Wall Opening Size on Rooms
In real-world projects, wall openings within rooms can sometimes occur. In Revit, small gaps in walls typically do not affect the creation of rooms. So, what is the size limit for these openings?
First, let’s examine openings along the straight section of a wall. For instance, the two images below illustrate the same scenario.
In this relatively simple case, the maximum allowable wall opening size for the room is 404mm (accurate to 1mm). Once the opening reaches or exceeds 405mm, the room will no longer generate automatically, and a room separation line must be drawn manually.
Next, let’s explore the more complex situation of corner openings. Corner openings present additional challenges. Currently, it is known that when openings of equal length exist at both ends of a wall, the maximum distance — measured from the wall end to the adjacent wall surface — is 190mm (accurate to 1mm). If this distance reaches or exceeds 191mm, the room will fail to generate automatically.
For corner openings where the distances on either side are uneven, the limit values vary and become quite complex. This area remains unclear, as Little Z has not yet established specific rules. For example, in the image below, the combined distance between both sides totals 430mm, yet the room is still recognized by Revit.
