Using Project Basepoint Coordinates in a formula

[rspierenburg]

Good day everyone,

I have a question, is it possible to create a Spot Coordinate that shows the Coordinates of the Project basepoint with an offset?

The reason I'm asking is that the formworker has requested that we provide coordinates for slab edges based off of three origins (one for each pour).  My initial thought was to place the Project basepoint at the first origin and then use Spot coordinates for the points.  But that would only work for the first pour.

Is it possible to have a Spot Coordinate show the location relative to the project basepoint +/- an offset?  IE (X+10'),(Y+20')?

Just curious.

Thanks,

Robert

You can do that, but I think you need to manage the type parameter for your X and Y value manually.

Could you please elaborate? I'm not sure what you mean.

You can include Elevation reading in a Spot Coordinate, if that's what you mean.  It's the Include Elevation Parameter. Check the box.

Not an elevation, just an offset in the X and Y axis.

Essentially I need three base points, one for each pour area.  So the coordinates for objects in the first pour area would simply be relative to the Project Basepoint, whereas objects in the other pour areas would be coordinates with an offset from the Project Basepoint.

I'm a little confused. A project has only one coordinate system.  Sounds like you want multiple coordinate systems. Maybe Linking in each "pour" via Shared Coordinates would be the solution here.

You can modify an existing coordinate tag, and add two parameters. But you need to fill these manually.

I'd do what you described at first, print. Move the PBP, print... repeat. Chances are your pour plan doesn't fit on a single sheet, assuming it is enlarged to focus on each pour separately. How many points are you looking at?

Another option is Autodesks Point Layout, familiar with it? Or cook your own with Dynamo.

...just wondering why this "formwork" guy can't work off of a Plot Plan showing building setback distances.  

[rspierenburg]

I figured that was the case.  I've since create a detail component family, which when tagged, shows the distance to an assigned basepoint.  A little more of a hassle but better than nothing.

As far as the formworker, I agree, typically we do a plot plan and they build off of that.  This building is a little more complicated and so I sat down with them and they asked me to do it this way so I figured I would try to accomodate them for the good of the building.

Thank you all for your input.
