Spot Coordinates Scheduling using Dynamo ( Error )

[Anonymous]

Hello 

I'm not familiar with creating dynamo scripts but with little research, I've created the shown script in the attached picture. This script has worked for one of my Revit models giving accurate shared coordinates according to survey point. however, I had wrong coordinates with the other models ! 

Could you help me know what's the wrong with this script ?

Dynamo can work with different scales. Smaller areas with larger precision or bigger areas with less digits.

So try a different scale within Dynamo (Settings > Geometry Scaling) and set it to more appropriate ranges (possibly Extra Large) and see how it goes

Thank you for your appreciated response. 

I've tried this solution and the warning disappeared but in vain. The numbers shown in the schedule are totally different from spot coordinates relative to survey point.

Can I find different nodes to get the same approach accurately ?

This would need some debugging and experimentation.

If it would be possible to send a stripped own version of your project (some of the foundations) on the proper locations and the locations as they are now in the project (survey / basepoint) and your script I could do some checks and see if I can come up with a solution.

Which Revit version and Dynamo version are you using?

I'm using Revit 2018 and Dynamo v. 1.3

Please find attached my stripped version of my project for your kind review.

I really appreciate your help.

It seems to be a different project than in your screenshots. Unfortunately I do not have 2018 on this computer

What you see in the script is that it calculates the difference between the location of the foundation and the location of the survey point.

Basically the only step to do now is to add the location of the survey point to these differences.

I have done this for x (E/W) direction and y (N/S). Result is as in the schedule above

Hereunder the script sofar. You will have to complete it and do more testing

It worked so well for all my models. 

I really appreciate your consideration.

Thank you.
