The OCAD Basics exercise teaches both basic and advanced drawing and editing functions in an interactive way. Many tips and tricks for working efficiently with OCAD are also presented.
The exercise file is therefore not only suitable for beginners, but also for experienced users who want to refresh their OCAD knowledge.
It can be found in the OCAD program under Menu File > Open Sample Maps in English, Swedish or German (OCAD Basics_EN.ocd, OCAD Basics_SE.ocd or OCAD Basics_DE.ocd).
If the files are not visible, please download the latest OCAD Update.
The specifications for the control descriptions have been slightly adapted by the International Orienteering Federation IOF and published as ISCD 2024.
The new symbol sets are valid from 1 January 2024 and are already available in OCAD (Menu File > New > Course Setting project for orienteering).
The most important changes:
Color of the control description on map now black by default (optionally still purple, see the Course Setting Options).
New symbol added for a map flip (turn the map over).
In this article we present different ways of drawing stairs in OCAD and what to look out for.
If stairs are drawn too small or too narrow, this greatly impairs legibility and the staircase can easily be mistaken for an impassable object (especially if the print quality of the circles is poor).
How is the stairway symbol defined?
Steps of a stairway shall be represented in a generalized manner. Contour lines shall be cut out for better legibility, if they touch stairways.
This means that when you are drawing stairs you should make sure that…
(1) treads are not drawn with too little spacing (min. 0.4mm)
(2) contour lines are cut out
(3) stairs are not drawn too narrow (min. 0.4mm)
(4) more than 2 steps are drawn (min. 3)
By the way: In addition to the symbol definition, the IOF O Map Wiki also contains images with correct and incorrect examples.
Draw steps individually or use stairway symbol
There are basically two ways to draw steps:
Use the symbol Step or edge of paved area (symbol 501.100) to draw steps individually
Use the symbol Stairway (symbol 532.00) to use a predefined stair width.
Use stairway symbol
The stairway symbol is suitable for straight staircases. The minimum width and tread width comply with the IOF specifications. The stair filling (colour. 44 Brown 30% – stairs) covers the contour lines, so no cutting of contour lines is needed. Problems arise with curved staircases (2) or staircases with varying widths. Often the predefined width does not fit and leads, for example, to thick edges (3). In such a case, the predefined stair symbols can be duplicated and the width changed afterwards. The whole width of the staircase should be visible and if not, building, walls, etc., should be reduced in size (4). When drawing, it is also important to note that the beginning and end of the stairs (1) must be examined and edited if necessary.
Draw steps individually
You get the most flexibility when you draw steps individually. For that, you can use the symbol Step or edge of paved area (symbol 501.100).
With the Stairway mode you can easily specify length, width and now also the tread depth (step distance). This is displayed at the bottom left of the status bar.
Individual steps can be copied (Ctrl + C), pasted (Ctrl + V) and moved to the correct position with the mouse or arrow key.
To use the OCAD Route Analyzer 2.0, course setters need a current map as well as a Digital Elevation Model (DEM).
This is loaded into the map or course setting file and ensures that the climbing and slope gradient are included in the route calculation. The DEM is typically created by the cartographer and has traditionally required a lot of memory.
The DEM can now be optimized and compressed without loss of quality for route calculation. This significantly reduces the file size of the DEM and makes it easier to share. The optimized elevation model can also be embedded directly into the map or course setting file, as is already possible with layout images.
