How to Unhide and properly Change/Manipulate Revit coordinates(Project Base Point and Survey Base Point)(04 of 10)
In the first post(01 of 07) of the Revit-Coordinate System Series, I've explained what are the different coordinate systems(ProjectBase Point and Survey Base Point) in Revit and how all the elements in Revit take a relative reference to Project Base Point(PBP) and Survey Base Point(SBP).
This tutorial explains how to properly manipulate/move those points
Follow the following steps to properly Change/Manipulate these points:
This tutorial explains how to properly manipulate/move those points
Follow the following steps to properly Change/Manipulate these points:
- Go to a plan view where you feel comfortable with the orientation of the project.
- You'll need these points to be visible in the plan view to make any changes to them. You can either use the Reveal Hidden Elements button or Change the Visibility Graphics settings.
- To unhide Project base point & Survey base point, press "VV" to open Visibility/Graphics Override window.
- Look for "Site" and expand it to find "Project Base Point" & "Survey Point"
Visibility/Graphics Override - Select the point that you want to edit/change which will reveal a Gizmo to move the point in X, Y direction, along with the information on the location of those points.
- But before moving either of the points, you might notice an icon similar to a clip when you select either of the points. This indicates how moving the respective point affects the entire project, which is explained in detail in another post.
- If you'd like to move the location of the project relative to the Survey base point i.,e keeping the Survey point the same but move the origin of the project then you need to move the Project Base Point. There are 2 ways to move the PBP
- Moving the PBP in its clipped state:
This method is used when you want to move all the elements in your projects relative to the PBP i.e., this will move all the elements in the project but keeps their relative position(X, Y, Z) with respect to PBP unchanged. - Unclipping the PBP and moving:
This method is used when you want to move just the origin of all the elements i.e., this just moves the PBP which means that the (X, Y, Z) positions of all the elements will be changed. - If you'd like to move the project to an entirely new location on the Map/Earth, you need to move the Survey Base Point. There a 2 ways to do this similar to PBP.
- Moving the SBP in its clipped state:
This method is used when you want to move all the elements in your projects to a new location on earth but keep the relative position of the elements w.r.t the SBP unchanged. - Unclipping the SBP and moving:
This method is used when you want to keep the elements at the same location on Earth but move your Survey Point to a new location.
Head to the following post to understand in details how moving the SBP & PBP affects the whole project.
