Symbology

kavereeGIS — Tue, 19 May 2026 15:05:42 GMT

I am working on a DGN file, and I was looking for the same symbology. Any tips would be appreciated. I was trying to format all symbols and sizes, but it is not working.

For a DGN CAD feature layer in a 2D map, the usual reason “formatting symbols/sizes” doesn’t seem to work is that size is being driven by a size variable or you’re running into symbol display unit expectations. Try these checks:

1. Remove any attribute driven size

Contents pane → right‑click the CAD layer → Symbology
Go to Vary symbology by attribute → expand Size (or Marker size / Outline width) → set Field to <None>

2. Be consistent about symbol display units

In 2D, point “size” is in the current symbol display units (for example points), which won’t necessarily match CAD/DGN design units 1:1.

3. If symbology changes won't stick, recreate the layer

Export/duplicate the data and re-symbolize (don’t re-import the same symbology if the layer is behaving inconsistently).

Thank you Robert,

This surely helps. I have another doubt similar to this. I was trying to export the features into DGN, but my features in the DGN are sized very small. I think this is happening as the ArcGIS takes features size are points based where DGN is metric based, is that why DGN could not read the feature size? Or does the Pro map displace limits has something to do with this? I tried removing reference scales and increase the feature size but still the DGN has miniature features.
