Referencing sections/ elevations to SEA LEVEL

Anonymous — Tue, 30 May 2023 08:06:00 GMT

Hello!
I am trying to have my elevation markers in sections and elevations to reference the Sea Level, not my project zero. I know how to change the markers' properties to do this, but the sea level of my project is wrong. Instead of reading 195.50' at the ground floor, it reads 23' (for example).

How do I change the sea level of my project? I suppose i could move my entire project vertically to the correct location, but i am trying to avoid that. We have Hotlinks connected, and our story settings are fairly complicated. Im sure moving the building up is not the way to go anyway. Maybe there is a simple answer to this, where i can just set the sea level.

Any help would be great. Suggestions on how to solve this problem would be appreciated too.

Thanks in Advance

As I recall it's in Options>Project Preferences>Reference Levels & Project North.

I just wanted to get a feel for others' experience out there...

While editing a TERRAIN MESH in 3d and with the COORDINATES BOX set to show SEA LEVEL... I cannot adjust the height of a point by simply typing in it's elevation above sea level... The number get's interpreted as an elevation above MESH BASE...

This seems extremely counter intuitive and useless...

I may be missing something, but I've tried a number of ways and the only real way to make adjustments is knowing it's relative height to the mesh base.

Even typing in 1'+ while in SEA LEVEL mode pushes the point to the sea level elevation above MESH BASE...

Let me know if I've explained this coherently...

Looking forward to your comments.

Duane:
Seems to work correctly for me in 3D (and 2D). I select the point, choose "elevate mesh point" from the pet palette and type the sea level elevation in "Z".

...and BTW.. you were RICKROLLED my friend.

I've found the best solution to the shortcomings of reference levels is to make project zero the same as sea level.

Just add a 'buffer' 0. Story (1. Story in the US?) called something like 'Distance to Sea Level'. Then give that story a height that matches the distance to sea level and uncheck the story level lines. Now you don't have to reference elements, including elevation and level dimensions, to anything but project zero. And if that distance ever changes you only ever need to adjust it in one place and everything updates.

The only time it becomes an issue is when IFCs are imported, but they're easy enough to elevate.

Sounds dodgey, but it works a treat. Give it a test and see what you think!

Have I missed something?
Level dimension still gives me numbers from Project zero.

For your DISTANCE TO SEA storey, try making the elevation 0 and the height to next 704.
