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:

  1. Go to a plan view where you feel comfortable with the orientation of the project.
  2. 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.
  3. To unhide Project base point & Survey base point, press "VV" to open Visibility/Graphics Override window.
  4. Look for "Site" and expand it to find "Project Base Point" & "Survey Point"
    Visibility/Graphics Override
  5. 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. 
  6. 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.
  7. 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.
  8. 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.

Power Query - "SUBSTITUTE" Function: Remove/Replace multiple values in a column in One Step.

Often times, when you get data from a source, there will most probably be something incorrect that needs to be fixed using an ETL process of Power Query. And most of those transformations would require either Replacing or Removing string's that are not necessary. For example, if you extract any financial data from a source which has multiple currency symbols, there's a chance that the numbers get extracted along with the currency symbols like "$700"/"€700" instead of 700. And these type of cases makes it tough to Transform the Data to our wish as the value will be considered as a text instead of a number. In those type of cases, we would most likely have to create multiple steps to remove the multiple currency symbols from the Column. But thanks to the solution provided by Marcel for one of the questions posted on Stack Overflow, with a little manipulation of the Query language (M), we can replace/Remove multiple strings in one step using the List. ...

Grasshopper: Voronoi Holes on a Planar surface

One of the best natural examples for a Voronoi is the Wing structure of a dragon fly.Grasshopper can help us to build a shape like this in Rhino. Image Courtesy:  The Pond blog Grasshopper by default has a node for Voronoi, we just have to prepare the necessary information to feed into the node. The following example shows how to create a Voronoi shaped holes in a surface Create a planar  Surface  from rhino or grasshopper Randomly Populate the surface with points using the  Populate 2D  Node Feed the surface and the points into the  Voronoi  node and feed a number slider too to adjust eh radius This forms the required Voronoi structure which you can edit the number of points or radius. To create the holes we need to offset each and every inner portion towards its centre using the  Scale  node We can find the centre of each of the inner portions using Area node I'm not sure why but using the offset command su...

Grasshopper: offsetting curves on surface vs scaling curves on surface

Though in Grasshopper Offset and Scale are two different node functions, when it comes to a planar surface, the results of the both are similar. But, I found the " Scale" node to be effective when you want to loft the resultant curve with another. The following images show the different results of a Voronoi structure that yielded when scale and offset nodes are used. When the Offset node is used When Scale is used

Group and Scribble in Grasshopper & Rotating scribble

Grouping & Scribbling in grasshopper can be helpful, especially when your document is filled with hundreds of nodes with wires going all around the screen. Often you might find it difficult to locate the set of nodes you'd like to adjust or alter for your project. So grouping the nodes and annotating the groups would be a nice idea to keep your document organised. Grouping In order to group a set of nodes, you just select them and right click on the screen(not on any of the nodes). You'll find the option to group. You can even name the groups just by right clicking on the group. Although naming the groups would be enough to identify the group. The name bubble of the group will disappear when you zoom too far out. So, the solution to be able to identify the group from a zoomed out fairly far is to add a scribble(with a text height of min 25) in the group.
