Question

DGN v7 writer rounds coordinates, which causes the file to end up a little wrong in the world

Hello!

 

When converting DWG/DGN v8 files to DGN v7, the coordinates in the v7 file are rounded, which causes the file to end up a few centimeters in the wrong place.

I want the v7 file to have the same coordinates as the v8.

How can i solve this?/ What is happening with the transformation that casuses this?

 

The difference between DGN v8 and v7The image is very zoomed in, but there is a difference.

 

Regards,

Gustav

Hi @gustav​,

The v8 version of DGN files has a much higher resolution than v7, so the standard scaling and global origin in the seed file may cause some rounding in the v7 output. You can override the seed file settings with an optimal setting for your data by setting Compute Optimal Seed File Parameters to Yes in the v7 writer. This will eliminate the difference between the input and output.
