Angle from true north

[TasnimTarannum]

Is it possible to get angle of its orientation against a vertical line from north to south. Like spot coordinate.

u can switch view to True North and add a vertical line then place an angular dimension between that line and any a component which has a side parallel to project north. This serves same purpose in indicating true north and any other angle as spot annotation does with coordinates.

I am doing that but requirement is automated angle like spot co ordinate the it shows North East value same way the angle will show along with north south value

You can use a parametric north arrow modeled in a generic annotation family see steps below

• Associat the arriw with an angular parameter "True North" (Type parameter considering that the true north will not change from one view or sheet to the other) 
• add a lable with the parameter above 
• load into project
• Place an instance(s) where needed
• Go to the site plan and select the project base point >>> copy the angle to true north
• Select the generic annotation >> Edit Type >> past value into the "True North" parameter >> hit ok (you can replace this step with a 4-5 nodes dynamo graph)

it should then populate everywhere you placed that annotation and on/in any future annotation you place

PS: you would need to create new types for

1. new sites if you have different design options each in different location
2. and a type for the site plan which in most cases is set true north vertical upwards ie: angle value in this case is 0 degrees

Thank you for your response. I’m not very skilled in Revit, so if you could elaborate a bit more, it would be very helpful. I understood how to find the true north angle and opened the generic annotation template, but I couldn’t find any such parameters in the label field.

Why don't you:

- switch the plan view orientation to True North

- place a North arrow symbol family on the line you want to report, the North arrow pointing North

- place a angular dimension from the North arrow to the line

- switch the plan view back to Project North?

You need to create it.

My Christmas gift to you...Try the attached family (Generic Annotation) you can add it on 1 sheet then copy/paste to selected views >> select sheets with floor plans where you need to place the arrow. The angle is a type parameter ie: changing it once will change on all sheets. It has 2 types:

1. Site views on sheets (where north point usually always UP/Vertical ie: 0)
2. Floor Plan View on Sheets (Where usually project north is used . You will enter the Angle to true North you copied from Project base point into this type)
3. If you have several site (ex: several design design options or from different linked topo/site files) you will have to create a new type per Site/DO. If not, simply disregard this step

Alternative to placing on the sheet and/or placing an instance every time you create a sheet, you can nest it into the Title Block and map the Angle Parameter to the Title block.
