Before drawing choose one of the 26 colors.

You can use the following editing tools:

Paste: Paste a selection of pixels
Open Paint: This button opens the Paint application of Windows. You can draw an icon in Paint. Make sure, your Paint document has the dimensions 22x22 pixels to get a satisfying result. When you are finished with drawing, select and copy the icon. Now you can paste it in the Icon Editor of OCAD.
There is an easy way to get an icon for a point object. Simply use the Make screenshot for symbol icon function in the Symbol Editor.

When displaying maps, OCAD uses the colors in the color table in a specific order; objects which use the lowest colors in the table are drawn first, objects which use the colors at the top of the table are drawn last. The advantage of this technique is that lines or areas can be omitted automatically. This is especially beneficial when drawing road junctions (cf. below).
- Select New in the File menu.
- In the New Map dialog window, double-click empty Symbolset.ocd.
- To edit the color table, select Colors in the Map menu.
- To create a new color, select Add in the color table and enter the name (e.g. pictogram white foreground) and CMYK value (e.g. blue 0/0/0/0) of the color.
- You can change the position of the colors in the color table by clicking the Move up and Move down buttons.
If two roads intersect at an under or overpass, only the lines of the lower road should be omitted. By moving the position of the color upwards or downwards, you will be able to influence these effects:
- Intersections: If the color of the filling is located above the color of the side lines in the color table, the side lines in the area where the roads cross each other will be omitted automatically.
- Overpass: To ensure the side lines are not omitted automatically, a new color must be defined for the side lines of the overpass. This color must be located above the filling color in the color table.
Learn more about colors on the Colors page.
If you would like to assign a color which does not yet exist, to the new symbol, a New Color will need to be defined.
Each symbol must have a unique symbol number between 0.001 and 999999.999.
