Here is the main supplement to explain the adjustment of the project base point coordinates to the real projected coordinates in Autodesk Revit 2018 mentioned in the previous ArcGIS Pro2.7 Revit data processing points .
The situation I encountered here is as follows:
(1) There are vector basic data when modeling in GIS, that is, some points and lines. Among them, one point is the reference point (standard point) for modeling, which is when the modeler is modeling in Autodesk Revit All refer to this point. You can view the actual projected coordinates (Xa, Ya) of this point in ArcGIS Pro.
(2) In Revit software, there are two situations.
The first, the base point of the model project is this standard point:
In this case, you only need to modify the coordinates of the project base point to the Xa, Ya previously obtained in Pro (of course, first adjust the unit to meters).
In the second case, the project base point of the Revit project is not this standard point.
If there is no standard point drawn in the project, you can draw a point through the measurement tool to check the coordinates:
This situation is more complicated. First of all, we remember that the project base points in Revit are Xb, Yb, and the standard points are Xc, Yc. First calculate the difference between the known coordinate point and the project reference point:
Xc - Xb = Xcb
Yc - Yb = Ycb
Then use Xa and Ya in the GIS to participate in the calculation, and move the project base point to the position of the standard point in the projected coordinates:
Xa - Xcb = X
Ya - Ycb = Y
Then, similar to the first case, you only need to modify the coordinates of the project base point to X, Y. In this way, when the Revit data is imported into ArcGIS Pro, it can be guaranteed to be in the same position, and then it can be fine-tuned through the Move tool of Pro.
