PROJECT BASE POINT and SURVEY POINT: The good, bad and ugly

These points have given people more trouble in Revit than the stair tool and railings combined. There is a built in issue I have with these and yet, with understanding, you can learn to use the Project Base Point and Survey Point to coordinate projects.

I have been looking for this info forever without luck, and now I am 100% sure no even Autodesk people can explain their own work, shame on them. You are the best. Keep up the good work. From Toronto.

[@depasser3]

Mike, take a course of land surveying for better understanding coordinate systems

[@luissosa308]

I just came across your video and must tell you that the clarity that you have when talking about something as complicated as the Coordinate system, made my day. I'll make sure to follow your videos and watch the previous ones. Thanks for making sense of complicated issues. Happy new year 2024

[@draytonpatriota9724]

Finally, someone to make sense of this apparently confusing subject! Thank you!

[@user-wd4lw6yo4y]

This is Gold, pure Gold. Thanks Mike and please keeping making such a great content. Its helping many of us.

[@mustafizrahman252]

Now I have understood the use of these two wired points. Great video with a clear explanation. Thank you, Mike...

[@cathychoi6959]

you are the ONLY one, explained the Revit coordinates very smart way!! very appreciated it! ❤❤

[@miketaylor8211]

You're very welcome!

[@alt5karim]

You are the best , you really love what you are doing. Thank you sir!!

[@femiosewa6948]

This thing is doing my head under and I have been using Revit since 2007!! But this is a good breakdown. Thanks

[@diegoarias1725]

Been working in construction for 21 years, we never work in Lat and Long, We only use Northing easting and elevation.

[@palmtree1126]

Hi Mike. This is my first-time using Revit and after attempting to follow the workflow provided by Autodesk to set up a project, I ended up on KZbin listening to teachers. Didn't take long :) Although you are ranting about it, I found the video not only funny and entertaining but also very informative about 3 silly little points. Anyway, I subscribed to your channel and look forward to watching your other videos on KZbin. Paul

[@kobusdupreez6534]

From south Africa. Finding your channel the best to assist me!!!

[@miketaylor8211]

Happy Revitting! I hope the very best for you there in South Africa!!!

Survey points are from State Plane. Not the Equator. Not the Prime Meridian. The Earth is not a plane (despite popular social dissent). Measuring over the curved surface would give you wildly different locations depending on whether you assume north dictates or east-west dictates. State Plane locates the project on the same coordinate system as the roads, utilities, civil works, and other buildings in your state or region. The location is not arbitrary. It's a plane that is projected onto the curved surface such that the ellipsoidal distortion is no more than 1:10,000. If you're in an area that does not have a coordinate system, you can use UTM.

I love your energy Mike. Thank you from Dubai.

[@MN-oy9dr]

👍great tutorial, as always, Mike! THNX 😃

[@freddiesan]

Fantastic, thanks a lot friend. 🤛🏼

[@iftekharkhan8879]

Excellent videos sir...thanku v much

[@arunrajrajagopal5845]

What a show! Even Autodesk itself doesn't have a proper explanation for survey and project base points and how to set them. Additional note: We can link our project to a real world Location by using Project Location tool*.

[@benzonjhermogeno]

Yeah project location tools is for shadow and solar analysis only

[@cesarenrique3987]

This guy is a Rock!!! thank you so much

[@ssnanj8014]

Thank you

[@nitishsharma4832]

Nice explanation!

[@Ab_Def_]

In the UK, all surveys are produced using Northings and Eastings, that is, distance N&E from the national survey datum, so placing the survey point at national 0,0 means setting out coordinates report their correct position (in national coordinates). This is perfect for UK projects, but strange if US surveyors use a different system.

[@esbenbestseller6067]

Fantastic video!!! I finally got it :D I'm wondering if you have maqde the video about geolocating the project that you talked about in this video?

[@rawezhful]

Hi mike, thanks for your explanation, we're still waiting for the video you talked about 6:13 to locate a project on real world coordinate

[@Tuba-nl1tc]

You are the best.

[@NVapi1]

Can you go over internal point and what is it use for?😊

[@nehama87]

Hi. Love your videos! do you have a video showing the workflow for Geolocating a project?

[@miketaylor8211]

Hi Nehama!! Yes, I think I do have a video for Geolocating a project. (I can’t remember! Lol) Do a quick search.. if you don’t find one, I’ll make one!

[@Duke-The-Jaguar]

Love from Nepal and Mt. Everest.

[@yveslaurentisidro]

I think the reason why autodesk did not use the lat and long because realworld or the earth is round while the Revit or autocad work space is plane that's why they use NE

[@draytonpatriota9724]

Hey Mike, Can you share your video for geolocating a project? ( or create one?;) Thank you very much!

[@iftekharkhan8879]

Hi sir plz solve my prib.i saw the cadd and the corner of the building is 19'6" nd 20'8" ok...but when i measure itsshow something else in the cadd file should i and when u change the UCS posiy to red dot in cadd file then the corner of the building show the exact set back from o.o..so we have to change this before export to revit or we should leave as is it?? I have many confusion sir regarding this....thanku sir

[@mrkickback2010]

Thanks. Survey dwg most often will be provided well after arch locates survey point. Arch then relocates survey point to new location once they receive civil backgeound. What is the best workflow for consultants to relocate their survey point to match arch. Thanks again

[@miketaylor8211]

The consultants can link the Architecture model into their models and when they are exactly aligned… they can AQUIRE the coordinates. It will lock the two files and move the base points.

[@reutmikey7861]

hey mike i turned on the v/g base and survey point ... and there is only the the survey point.how can i find the base point?

[@LouisBanks-mb9gd]

mep elements use the internal origin

[@RoalfW]

the survey point is set relative to the internal base point

[@nakulbabooram1455]

I've a question. How it works when you are using a 3D CAD site plan in an ( elevation view eg: South Elevation or any ). Because when you generate the 3D cad site plan into Revit and acquire the coordinates, the Site plan is on the Top of all the Levels. How do we move the Survey & Project base point & the levels without the Site plan moved together in an Elevation???

[@miketaylor8211]

The linked or imported CAD files will move when you move the Survey Point... even if they are pinned. So you will need to move it BACK to where it belongs with respect to the Survey Point. I know.. it's crazy.. but it just doesn't stay in it's location with respect to the real world.

[@harutanaka3647]

i accidently make workset to my project, how can i remove it. so i dont need to go through workset saving process?

[@miketaylor8211]

To shut off the Worksharing function... save the file and get out of it. Then when you go to open it... Open it DETACHED from Central. A dialog box will ask you if you want to remove worksharing!

[@padmakkr]

Hi..sir...while receiving Arch Model,How do we know.This file contains share coordinates or Project coordinates? I mean while linking Archi model to our mep model, What linking option we need to select? That how we Know. Can u please clarify.it will be realy helpful

[@miketaylor8211]

If you load in a model and tell it to load based on 'Shared Coordinates'.. it will error if the two files are NOT sharing coordinates. You can acquire the shared coordinates from the Architects file after you load it and make sure it is perfectly aligned with your model (easiest before you have any geometry because then it doesn't have to be aligned!). The file will stay connected to the Shared Coordinates until you tell it NOT to. So you are safe after that.

[@padmakkr]

@@miketaylor8211 Thank you very much for the reply

[@PaulineSmith-ex6eb]

Any chance you can explain the internal point?

[@miketaylor8211]

There is an Internal Base Point built into Revit... you can't actually change it.

[@user-or8wd2wr4g]

he was PISSED WITH AUTODESK. LOL
