Relocate the project!

Hello,

 I am very confused with the coordinates in Revit. And now I have started to explore this more.

 

I have my building in an elevation 0.0 but I did my toposurface in the correct elevation. So now I need to move my building only in the coorect elevation. I tried the relocation project option, now my building have the elevation that I want but the toposurface is still higher than my building.

 

Could you please someone help me?

 

Thank you in advance!

You should move the topo down instead of moving the building up because it can break a lot of things.

How I can do this..?

I went in an elevation view and tried the move commande but nothing happened.

Did you untick Constrain box when you moved the topo in an elevation view?

Well I moved the toposurface and after i did relocate project to have my toposurface and the bulilding in the correct point...

It is wrong?

Hi..

 

Move all the levels to correct Elevation and your building will set to correct heights..

Its good to do this in initial stage..

 

other way is move that topography down, but that may not give you correct spot elevation

as per topo... For this you may Create a LINK Topo file, and Link it to Building..that way you 

will always have Levels coming from "TOPO Link"

Yes..

Now I place the building and the toposurface in the correct elevation but my toposurface point don't have the correct value.

But it is strange because I relocate the project in the elevation that I had before my toposurface..

 

So I changed the elevation of the toposurface (I put it down to the bulding) but after I brink all the project (building + toposurface) in the elevation that I had my toposurface

@Corsten.Au,

 

I didn't understand very well this ' or this you may Create a LINK Topo file, and Link it to Building..that way you

 Thank you in advance!

Unclip the project base point and move it down.  Then reclip it.

Spot elevation shows as per project ..and not as per link.

Consider in project : ground floor is at 10’-00
And liked unit is ground floor 0’-0”

When you link unit , to project .. and match ground floor of unit to ground floor or project .. you will get spot elevation as 10’-00”

For topo.. if you have done heights correct Then once you link to the project you need to move it to match with level of topo as well..
next level is level as per project and level as per survey ..
Ex: you model unit ground 0’-0”
Level 10’-0”
Roof at 20’-0”

Later you come to know the survey and ground floor should be at 55’-0”
Then just change the survey point elevation to 55’-0”

That will change levels of unit relative to survey ..
Ground floor 55’-0”
First floor 66’-00”
Roof 77’-0”

Hello all,

 

Back to this subject, as after a lot of tests I cannot find the correct workflow to have my toposurface in the correct level and my building too.

 

This is what I do:

 

 

-Link CAD the floor 1 center to center. 

-Rotate the true North.

-Acquire coordinates in order to have the Project Base point with the correct X,Y Coordinates. [exp. X: 1180000000.0 Y: 2700000000.0  Elev: 0.0 ]

- Unclip the Project Base Point and move it in the corner of the building.

-I start to model the buiulding in the elevation 0.0

-When I finish the building, I Specify Coordinates at a Point Command and I give an elevation 615m.

 

so now the Project Base point has the value X: 1180000000.0 Y: 2700000000.0 Elev: 615.0 

the Survey point has the value X: 0.0 Y: 0.0 Elev: 0.0 

 

-Now I want to create the toposurface. So I link the CAD [ the contours of my toposurface are between 618m - 613m].

 

If you see the attachment you will notice that the toposurface is higher than my building. This is what I cannot understand. As I moved my building in the 'correct elevation' why the toposurface still remains higher?

 

 

Your ideas could help me..

 

Thank you in advance!

Well I also noticed that when I put an Annotate Spot Coordinate with a Cordinate Origin 'Project Base point', the building is in the elevation 0.0 and the toposurface in the elevation 615.0

.

If I change the Coordinate Origin to the 'Survey Point'. The building is in the elevation 615.0  and the toposurface in the double distance 1230.0.

Can anyone help me to understand this workflow?

 

Thank you in advance!

You almost have it. You did draw the terrain/imported your CAD in Elev= 0.0m Project Coordinates. When you changed your project Base Point to Elev=615.0m, you moved your CAD 615m too high. If you already created your terrain, you would just displace it in an Elevation (if you can't check if it is pinned).

When you import a CAD, it is always in related to a Level. You can select it and in the properties adapt the elevation or you can create a new level in Elev=0.0, an assign the CAD files to this level. Because of that (we rarely want to have a level in elev 0.0 in our mode) it is sometimes a good strategy to have a separated rvt file with terrain (but if your project is simple, I don't recommend it).

@M_Perez , 

 

Hello, thank you all for your answers.

I absolutely miss something...In the Autocad I have in one plan both the terrain and the building. If I go in an elevation the building has a position Z: 0.0 and the terrain has a Position Z: between 618m - 613m.

 

So in Revit when I import this CAD link in elevation 0.0 I have the link- building in 0.0 and the link- terrain much higher (in 615m).

 

If I relocate the project or give an elevation value in the project base point [615 m]  the distance between the building and the terrain continues to exist. So my building doen't reach the terrain. 

 

(I know that a solution is to move the terrain lower...but I want to learn the correct workflow in order to create the terrain in the correct elevation in which my building is located)

.

 

 

Thank you in advance!

Could it be that the terrain an xRef in Autocad is?


I've never tried to import a file with xRefs, I would recomend you in that case to import the terrain file and the building separated and see what happens.

Hmm question... In AutoCAD file the 3D contours should be designed in the real height or in 0.0 ?

If you import your CAD file in Elev = 0.0 or move it there, then is real elevation right. But if you place them in your project +0.0 then you have to draw them in project elevation.

@M_Perez , 

 

I import/link the CAD in level 1 (which is the 0.0), I check also this from the properties:

Base Level: Level 1 

Base offset 0.0.

As I said, the CAD file contains both the building and the Terrain, you will notice in the attachment that the building is much lower than Terrain. 

 

In revit the building that I have designed is in the lower part of 3D with the CAD building.

 

So now when I change the Project base point in elevation 615.0  / or relocate the project my building and the terrain have always this distance.

 

 

 P.S. In AutoCAD I need to have polyline or 3Dpolyline?
