The updated International Specification for Orienteering Maps (ISOM 2017-2) has been published by the IOF Map Commission recently.
OCAD has implemented a new function Update Symbol Set to update maps drawn according to ISOM 2017 to the new ISOM 2017-2 standard. There will be approximately 15 changes to your symbol set.

The changes have also been adopted to the OCAD symbol sets “Orienteering Map ISOM 2017 10’000” and “Orienteering Map ISOM 2017 15’000”. So, if you start a new map, you work automatically with the latest ISOM 2017-2 version.

How to update Symbol set to the new ISOM 2017-2 standard in Ocad 11?
This new function is only available in OCAD 2019.
Please: Publish same “changes” image also using IOF standard = 1:15000. And not only in some unnormal scale 150% values.
=> Older Ocad users easier to make changes to own ISOM 2017 symbol sets without using calculating.
Thanks for the comment.
I updated also a 1:15’000 map and published a picture of the changes in our Wiki.
