Survey point doesn't work

Vojtech Slavik — Thu, 19 Dec 2024 12:43:28 GMT

Hi, could someone advise me on how to fix the Survey Point?

I have a project modeled near the origin.

I imported (in worksheet 2D) a site plan via XREF, which is positioned at the correct coordinates.

I moved the Survey Point to a known point, rotated it to align with north, and recorded the coordinates.

However, when I check the coordinates set to derive values from the Survey Point, they give me different values.

Does anyone know how to fix this?

My support team told me to do it differently—create a new model and link my current model into it. But that's not the solution I need. I need to have one model that can export both from near the origin and with the correct coordinates according to the coordinate system (Sweden = SWEREF 99).

Operating system used: Mac Intel-based 12 Monterey

Hi Vojtech Slavik,

Your survey point is set E -158800000, N -6551900000 from the project origo.

Your Coordinate27 object is set to show the coordinates of the place object from your survey point. So it will display the same values only if placed on the Project origo (0,0,0). Placed on the survey point the object will display 0, 0, 0.

Thank you for your response.

I still don’t understand.

Could you explain it to me in another way?

I entered the coordinates for that point, placed the object on "Coordinate27" exactly at that point, and set it to show the value relative to the Survey Point.
Shouldn’t it display the same value?

I also want to add that I rotated the north direction in the Survey Point.
The base isn’t rotated, so that might be a bit misleading.

My question is: why doesn’t Coordinate27 display the same value I entered?

I didn't think the survey point worked in a worksheet, it only works in the floor plan window.

Of course, I am using the Survey Point in the Plan!

The Worksheet is set as a Trace Reference, in with the XREF reference drawing which is correct in the world coordination.

My problem is that even when I correctly set the North direction and assign values to the Survey Point.

The Coordinate Object referencing to the Survey Point gives me different values in the Plan.
And I don’t know why.

Are your Eastings and Northings the wrong way around? X coordinates should be East and Y coordinates should be North?

It looks like the co-ordinates are incorrect but nit wildly wrong which would suggest there may be a rotation issue somewhere. It also looks like the rotation of the North may be incorrect assuming the grid on your screenshot should be North/South/East/West.

If you use the survey point tool on plan to firstly rotation the North arrow to follow the same north as your grid and then offset x and y to the same orientation as the north using minus figures it should then give you the correct co-ordinates. I'm finding it difficult to explain.
