@Austin thanks for the clarification. the difference between the shared and internal origins is clear and needs to be highlighted. You’re right that this video (having watched it again after some time) does not do that. i’ll see if i can make a follow up that better explains that distinction.

Decent tutorial for an intro to origins, however I am dissappointed that the fundamental information is incorrect. I guess it will work, but you are constantly confusing “project origin” with “shared origin.” They are two completely separate things, and also the reason why the upgraded 2009 model showed the “original” origin in 2010. It is not a residual Revit error. In 2009, you simply changed the “shared origin” by specifying coordinates and not the “project origin.” (Which is why it only works when you export/link using “Shared Coordinates”) If you would have turned on the “Survey Point” in 2010, which shows the origin of shared coordinates, it would have been at the 0,0 point you specified in 2009. Therefore, your comparison of changing the origin in 2009 v 2010 does not equate: you changed the “shared coordinates” in 2009 (which you can still do in the same way in 2010) and changed the actual “project origin” in 2010 by unclipping and dragging the Project Base Point. This is clearly outlined in Revit 2010 Help Menu.

Hi!
I struggled to set 0,0 point for exported DWG file. Your lesson helped me to solve the problem. Thank you.

Publishing coordinates post is up.

Fantastic!!!
Is there a link to a list of tutorials, including shared coordinates? Thank you very much.

Excellent coverage of origins related to file import-export. The location of a “world” coordinate system seems obscure in Revit 2008 and 2009. I have relied on it to coordinate multiple files in acad.

@Crawford, yes. Should be up next week. Thanks!

This was a very useful tutorial - thanks! Will you soon have one available about sharing coordinates, as you mentioned at the end?

That’s a great observation… and now that you mention it, coming up with a good use case as to when this would be useful in an every day design scenario would be a great tutorial as well. i think making people very aware of their function is the first step toward implementing them without fear. We’re doing some work with large campus models that require the use of these tools, but every time it is used as a singular operation… there’s no design objective with it. Any ideas?

Thanks for the tutorial, great information. I have noticed that even when I pin the Project Base Point the coordinates can still be changed using Specify Coordinates at Point. Pinning the Project Base Point only stops someone from doing a Position Relocate. On a related note if I pin the Survey Point I can’t change the coordinates using Specify Coordinates Point, however I can do a Position Relocation which will change the coordinates. Only way to truly lock the coordinates seems to be by pinning both the Project Base and Survey Points
I’m still trying to figure out the best way for out office to use these tools. I’m a little fearful because depending on the combination of pinning and paper pinning the two points; moving one will point affect the other point in different ways.
Love your tutorials, thanks again!

Hi Conor, thanks for the support! Feel free to throw out ideas and questions too.
Good luck.

VERY interesting post.

This is exactly the kind of high-level, actual usage of Revit in design projects that I am looking for. This kind of thing make seem obscure to new comers, but in order to bring Revit to the level of usage of Autocad in a design office, it is vital.

Great work, as always!
