Drawing modes in OCAD

To draw an object in OCAD, you need to select a drawing mode. Since the last Service Update, there is a tutorial file to familiarize beginners with the different drawing modes. But also advanced OCAD users will make one or the other discovery.

Therefore it is definitely worth a look!

The Drawing modes.ocd file can be opened in the folder OCAD menu File > Open Sample Maps.

Improved transfer of OCAD Team licenses

If OCAD Team licenses are transferred frequently, it can happen that a license gets “lost”. This can happen, for example, if a user does not correctly transfer or block the Team license.

Users of Team licenses can now select the option Deactivate this license automatically when closing OCAD in the License Manager. This will automatically release the Team license when OCAD is closed. The license must then be reactivated when OCAD is started again.

Export of Geospatial PDF

When exporting a PDF from georeferenced OCAD maps, a Geospatial PDF (WGS84) according to ISO32000 is created automatically.

The Geospatial PDF can be loaded e.g. on a mobile phone in the app Avenza Maps as a map or it is possible to measure distances and request coordinates in Acrobat Reader.

Multi-directional Hillshading

A hillshade is a shaded relief picture of the surface. Important for a hillshade is the position of the imaginary light source, which is taken into account for shading the image.

Normally, the direction of the light source is 315° (north-west). Since the Service Update 20.5.3, it’s also possible to choose the option Multi-directional. It is a composite image made up of four images in which the light source comes from different directions. Like this, the terrain is more realistically represented, and overexposed and nonilluminated areas of the map are more balanced.

In OCAD, Hill Shading can be created from the DEM menu or from the DEM Import Wizard.

How to use OCAD and LiDAR to Calculate Climbing for Courses

In order to indicate the climbing for courses, many course setters invest a lot of time to manually add up the climbing along the optimal route. If a terrain model (DEM) is available, this can be done easier with OCAD. With the following workflow, which is also possible in the OCAD Course Setting Edition, the climbing can be calculated automatically to a certain extent:

  1. Start a course setting project, open a background map and draw a course.

2. In your course setting project, go to menu DEM > Open and open your terrain model (* _DTM.ocdDem). This file is generated during the LiDAR processing.

3. Now draw a line with the optimal route from start to finish. This has to be done for each course. Use any line symbol in the symbol box or create a new one.

4. Select one of these optimal routes and go to menu DEM > Create Profile. You will get a Total ascent value, which you can enter into Course Setting > Courses > Climb used.

In the Courses dialogue, there is also a Climb calculated value, which is just calculated automatically by adding the net ascent from each control to the next one. The value that is entered in Climb used will show up in the control description.
