I was reading this post at https://communities.bentley.com/products/microstation/f/z_-archived-microstation-v8i-forum/69397/microstation-v8i-design-file-advanced-setting-resolution and was wondering how someone would have determined that changing the Design Resolution setting “changes the size of existing geometry in the model”, as stated in this post? The only thing that I have noticed from tests I’ve done on this is that these settings affect the ability to zoom in as close as one might want to in their model. I have done some minor testing on this and below is what I have found . . .
Our company has their seed files (2 – one for State Planes East and one for State Planes West) for surveys in the state of Alabama with the following Design Resolution settings . . .
However, with the settings shown above, my ability to zoom in as much as I would like on certain elements are hindered. From what I have tested, simply changing the Advanced Settings > Resolution: to the settings in the next screenshot does nothing to the size of the geometry, but does allow me to zoom in closer to objects than the previous settings do . . .
Since I am relatively new to MicroStation (maybe 3 years total in the last 10 years, but a 25+yr. AutoCAD user) I am not sure exactly why this is so, but I have two test drawings created from the same seed file with the only changes being made to the settings being those shown in this last screenshot. Distances I’ve measured in both of these test drawings seem to be exact, and Google KML files created from both seem to appear in the exact same location on Google Earth. How could this be so if changing these settings would result in changes in the size of the geometry as the post about has stated?
lets take your fist screenshot.
If you drew a line 10 feet long with the settings from that first screen shot, it would be represented in the file as 120 points (resolution 12 per foot).
Now if you change the resolution in the file, the line is still 120 points long, you have just changed what the points represent.
Lets say (to keep it simple) you changed the resolution from 12 to 120. The line is still 120 points long, it will just measure different. In the first case it would measure 10 feet and in the second case it world measure 1 foot.
Hope this makes sense.
Here is another article that discusses some of this in detail:
