Sketch Layer Introduction
OCAD Sketch Layer is designed to be used for field work with a tablet and a pen. There are just two simple tools: A drawing
pen and an eraser. Different colors and pen width can be chosen for drawing. The main approach is to make field
work as fluent as possible by minimizing tool/symbol changes.
The Sketch Layer is a separate drawing layer on top of the map, and its features are stored as polyline vectors with a line width and a color. The sketch features are not assigned to any map symbols.
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!
Choose the Pen button in the Edit and Drawing Toolbar to show the Sketch toolbar.
Sketch Pen Tool
Choose the sketch pen tool for drawing. Drawing start when putting the pen on the screen and finishes with taking it away from the screen.
Sketch Eraser Tool
Choose the eraser tool to erase sketch features or parts of them. In difference to custom OCAD map objects, you do not need to select sketch features before.
Change the color by clicking another color square. The color rectangle in the left shows the selected color.
Select Pen Width
Change the pen width by clicking on a gray pen width field. The field with the selected pen width is shown in black color.
Show/Hide Sketch Layer
This button can be used do show/hide the Sketch Layer.
Auto Detection of Objects by Shape and Color
Turning on this 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
This function makes a png raster file copy of the current sketch features and loads 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.
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:
