Adjusting Project North, True North, and Plan Orientation in Revit

-

 How can I make West be Up in my drawings? OR North is Up in my drawings but it’s not 
“really” North. What’s the difference between Project North and True North? OR How do I 
get my project located to match my survey? 

Each Revit project file has its own internal coordinate system which by default is only known 
to the project. If your project is a stand-alone, you may be able to live with this internal 
system. By default, North is toward the top of the project and truly faces north. 
When you first start a project, you should specify the project location using either Internet 
Mapping, the nearest major city, or latitude and longitude so that you can generate location-
specific shadows if necessary. Note that you can add new cities to the list by editing the file 
SiteAndWheatherStationName.txt. (If you don’t have actual survey data, Google the latitude 
and longitude for the city you want to add.) 
If you’ve started modeling your project before you locate the project, you probably started 
modeling with the long dimension of the building running left-to-right and no regard to where True North is located. That’s okay. You can rotate True North by switching to the Manage tab and in the Project Location panel, choosing Position>Rotate True North. Note that the project orientation must be set to True North in order to do this. This will change the angle for a project relative to True North. You can then specify an angle on the Options bar or 
rotate graphically. 
You can then add a north arrow to your view. The arrow will point toward the top of the view, 
which is now set to true north. If you then change the project orientation back to Project 
North, the building will once more align with its long dimension running left-to-right, and the 
north arrow pointing to true north. 
If you subsequently rotate project north to reorient the model in relation to the view, 
however, the north arrow will no longer be pointing in the proper direction. To fix this, switch. Each Revit project file has its own internal coordinate system which by default is only known to the project. If your project is a stand-alone, you may be able to live with this internal 
system. By default, North is toward the top of the project and truly faces north.

If you subsequently rotate project north to reorient the model in relation to the view, 
however, the north arrow will no longer be pointing in the proper direction. To fix this, switch the view orientation back to True North, fix the direction of the north arrow (either rotate the 
existing arrow or delete it and add a new one), and then switch the view orientation back to 
Project North. 
In terms of placing your project to match survey data, there are a number of ways to do this. 
If you receive a CAD file with accurate survey data, you can link the CAD file, move it under 
the project to match your project model, and then Acquire Coordinates from the CAD file. If 
you simply receive survey data for a datum point in your model, you can choose Specify 
Coordinates at Point (in the Position split button in the Project Location panel of the Manage 
ribbon; see Tip #4) to accurately locate the building.

Spool Drawing creation in Revit

-

Yes, Spool Drawing can be created by Revit   There was a time when you need to use Autodesk Fabrication Software for creating spool drawing. That time is over. Now if you have a Revit model & you want to create Spool Drawing from that model them it is also easily possible. For creating spool drawing from Revit Software you need to follow the following steps:  Creating Item No tags for Pipe & Pipe Fitting & Accessories : In spool drawing we need to numbering every items & providing a Bill of Material of the items in a spool sheet. Into the bill of material we need to provide the details information of every item with their item no.     We can't add anything into the schedule until it is a share parameter so we need to create a share parameter for Piece No. After that we need to create a Pipe tag & an Pipe Fitting tag for showing the no value in spool value. For creating Pipe & Pipe Fitting tag we use the share parameter as ...

Why you should need to apply BIM at your Construction Project

Source:  https://www.saint-gobain.com/ What is BIM ?     B uilding Information Modeling (BIM) is a 3D model based process which gives Architecture, Engineering Construction professional an insight tool to more efficiently Design, Plan & Manage their Construction Project.In one word we can say Building Information Modeling is process of generating Digital Data for a construction work. Although if I say that BIM is only a 3D model based process then I'm not fully correct. BIM has another three dimension, Time(4D), Cost(5), As Built Operation(6D).
