Help to Offset coordinates from excel using vertex

Hi. I am trying to offset(Y  -6170000, X -130000) and extract coordinates from an excel file. I have used a vertex creator to generate X,Y and Z. It messes the coordinates up and doesn’t seem to work as it has worked with other readers I’ve used.

 

(In the picture the offset is disconnected.)

I would also like to change the colors of the various shape file segments in the inspector, are there transformer commands to do this?

PS. Is there a place you can upload workspaces to get feedback on them?

Hej,

 

 

I'm not sure what the problem could be, and it's a little bit difficult to tell when you've disconnected the Offsetter ;-)

 

 

However, the VertexCreator should work as advertised. Just remember that the Offsetter goes after the VertexCreator.

 

 

For most purposes, a screen dump works great, as you did here. If you need to share files, you could consider using a service such as Dropbox: https://www.dropbox.com/help/20

Sorry, forgot about the question re colors: Try using a FeatureColorSetter before the Inspector.

Thank you for your help David. I think the issue is that X and Y should be flipped. Something to do with CAD standards we export to. I will try simply reversing them in the vertex creator.

Hi,

 

 

yes, having to swap the x and y values is a common issue. From wikipedia (http://en.wikipedia.org/wiki/Geodesy#Coordinate_systems_in_the_plane):

 

 

It is geodetic practice—contrary to the mathematical convention—to let the x axis point to the North and the y axis to the East.
