OCAD Sketch Layer and it's tools are designed to be used for field work with a tablet and a pen. The main approach is to make field work drawing as ergonomic as possible. There are just two simple tools: Drawing pen and Eraser. Different colors and pen widths can be chosen for drawing.
The Sketch Layer is an own layer within the OCD file and its features are stored as polylines with a line width and a color. The sketch features are not assigned to any map symbols. The Sketch Layer is rendered on top of the map.
Windows Pen Settings
We recommend to turn on the Ignore touch input setting: Windows settings → Pen & Windows Ink → Ignore touch input when I’m using my pen. This ignores touch inputs as long as the pen is near the tablet screen.
Touch inputs are also ignored as long as you wear gloves!
Sketch Pen Tool
Choose the Sketch Pen tool for drawing.
Sketch drawing starts with placing the pen on the screen and ends when the pen is lifted from the screen.
Show Screen Grid with a real world distance of e.g. 10 or 20 meters can help to estimate the distances.
Sketch Eraser Tool
Select Pen Width
Show/Hide Sketch Layer
Auto Detection of Objects by Shape and Color
Turning on the Auto Detection of Objects option will detect the pattern of some orienteering map point features and automatically add it to the map as symbolized point object.
The option is turned off by default and only available if the map symbol set corresponds to ISOM 2017 or ISSprOM 2019.
The tool expects shapes sizes of max. 50 pixels width/height. This corresponds approx. to the size of the symbolized point objects on the screen when working with a zoom factor between 8x – 12x.
Save as Image and Load as Background Map
Click the Save as Image and Load as Background Map button to make a PNG file copy of the current sketch features and to load this PNG file as a background map.
This may be used as a backup function while field work or if you prefer to have the sketch features in the background for drawing the map at home after field work.
The function requires that the ocd file is saved – it does not work for new untitled files.
White sketch features are only visible in the saved image if other background map(s) are loaded below it to get a contrast to the white background of the drawing area.
There is a new Sketch menu which contains just a few menu items at the moment.
This function can be used do show/hide the Sketch Layer. It's the same as using the button on the Sketch toolbar (which is not available in Course Setting and Viewer edition).
Delete All Sketch Features
This functon can be used to clean up a file from all sketch features. Note: There is no UNDO for this function! A message about this needs to be confirmed:
Option for Large Color Boxes in Toolbar.
