Become More Productive with OCAD in 2017 – Part 2

New Year resolutions that will stick

Here are some matters that puzzled me or other mappers, but were eventually resolved. Take a browse to up your OCAD productivity.

Multiple OCAD instances

After an OCAD update to a new version (such as 11 to 12), do not be tempted to run both versions simultaneously on the one PC. The same temporary file names are used by both versions.

Characters inserting/deleting 1 or more places away from cursor?

I use cartographic fonts and a few fonts with slightly quirky styles. For many months while editing blocks of text on maps, I blamed my laptop for letters being inserted and deleted 1 or more places from the insertion point. After moving to a desktop PC and having the same issue, I thought to ask Mark Roberts who replied ‘ligatures’.

Ligatures are 2 or more letters combined into one character. ff, ae, fi, ffi, ft are often combined in a font that enables ligatures. See Wikipedia for more. OCAD recognise ligatures as a single character whereas your OS and you are seeing it as multiple. So if I write difficult in OCAD using a ligature font, OCAD thinks the cursor is 2 characters prior (the ffi being a single character). Note that ligatures in a block of text are cumulative in effect.

A 25 second video showing a normal insertion and then a ligature effected insertion. Deletions are similarly affected.

Solution 1 – do not use fonts with ligatures.

Solution 2 – once you understand there is a pattern, it is fairly easy to edit small blocks of text with ligatures.

A DEM elevation profile is back to front?

You may have merged many segments of track, or drawn a long curvy track, only to find the profile depicts the opposite direction of travel.

This is because the elevation profile function uses the direction in which the line was drawn (or traveled in the case of GPX tracks). Simply Object>Reverse Object Direction and redo the elevation profile. It is also a symbol on the menu that you might know better as the symbol to reverse the direction of fence tags.

 


Aiming off

On a stressful day, this is a calming 5 minute video. Though I’m not sure which is the more calming – the scenery or the voice.
