Synchronization of IFC coordinates of models in the BIMvision browser
In BIMvision, you can read the coordinates of nodal points, such as element corners, give them new values and shift the model by the given values. It often happens that the component models are not made in one coordinate system, but – usually due to a designer error – with some offset. Before merging , these systems must be synchronized (the IFC coordinates of the models must be synchronized).

How to synchronize IFC coordinates in BIMvision?
Synchronization of IFC models can be done in the free IFC BIMvision model viewer – it is illustrated in the example below. The model of a small house was developed in such a way that its two parts were made separately. After loading both parts, it turned out that the models are shifted in relation to each other along the x axis.
The Measurement option calculates the value of this offset using the “Length: point-plane” function, which in this example is 0.47 m.
The model of the smaller part can be shifted to the larger one using the “Coordinates – Offset” function: select a point in the model that is being moved and enter the offset value -0.47. We can save the result in the form of correctly “glued” parts as one new model, saving this model in one file in the native .bvf format.
The options for reading coordinates, moving and changing the coordinate system are available in the free basic version.
Synchronization can also apply to industry models before they are merged into a federated model.
