# Thread: Spot Elevations

1. ## Spot Elevations

I have an architectural model with the Level 00 set at 6850mm.
I've linked it into my MEP model, collaborated (copy/monitor) all the levels and done my modelling.
When adding spot elevations, I've noticed that the elevations are "incorrect". The elevations don't report the height from the line of the Level 00 but rather from what would technically be the absolute 0. In other words the spot elevations are telling me that my piping is sitting at a level of 19620mm high whereas on site it would actually be mounted at a height of 12770mm (19620-6850).

How do I solve this? Is there a way to instruct the spot elevation to look at the distance from a level or is there a way to change either the MEP model levels (preferable) or adjust the Architectural levels (all relative to each other) sothat their relative distances between remain intact? (and hence the equipment related to the levels?)

I've tried duplicating the Level 00 type and making it a "survey point" at 0.0 but that hasn't made much difference to the figure reported by the Spot Elevation.

Ciao for now.

change the Elevation Origin in the Spot Elevation type properties?

3. Spot elevation origins are greyed out in my Properties. I've also kept an eye on the settings (under the ribbon) when I select Spot Elevations to place them. I don't see anything immediately useful for my dilemma.

This is frustrating.

4. Here's my tutorial on the subject:

5. ## Sorted - Thank you!

It was dead simple once I'd got my head around it.

Instead of attacking the problem from the view that the Spot Elevation tag wasn't doing what it was supposed to, I needed to accept that I'd not set the project up correctly and completely. There was nothing wrong with the Spot Elevation tag and what it was reporting and something incorrect with the Project Base Point.

So, step by step:
In Revit MEP project (not the linked architectural project) under View ==> Visibility Graphics ==> Model Catagories.
Check under the Visibility column for Site and expand the catagory by clicking the + sign. Make sure the Project Base Point is checked.
In the model area find the Project Base Point symbol. Looks like a circle divided into four segments.
Select this symbol and a paperclip plus x, y and z coordinates will appear.
Deselect the paperclip (sothat it has a line through it) and change the height (z coordinates) to what is required.
Select paperclip so that the model is attached again.
In Revit MEP project (not the linked architectural project) under View ==> Visibility Graphics ==> Model Catagories.
Check under the Visibility column for Site and expand the catagory by clicking the + sign. Make sure the Project Base Point is UN-checked.
...and you're done.

Include Spot Elevation tags and they should be reporting correctly from ground level. YAY! http://www.revitforum.org/images/smi...nbutthead1.gif

Again, thank you for the help!
