Show Impassable Features
This function is available for orienteering maps or course setting projects that comes in an official IOF symbol set.
This function shows a black/white image with all impassable features (incl. course overprint out-of-bounds features).
If the function is grayed out, that means that OCAD does not recognize your symbol set as an official IOF symbol set.
- OCAD checks for all IOF map specifications (ISOM, ISSprOM, ISSkiOM, ISMTBOM) that the first symbol of these numbers (101.000, 101.001, 101.002) is a contour symbol (brown main line without any gaps or double line)
- OCAD recognizes ISSprOM 2019 symbol sets if they contain the wall symbol 513 and ISSprOM 2019-2 symbol sets if they additionally contain the two-level symbol(s) 512.3
