Gears, cogwheels

[andrew]

From a QCAD user:

How can I draw gears (cogwheels) with QCAD?

[andrew]

QCAD itself does not have any special functions for drawing gears.

However, there are some useful websites with online tools or software for gear construction with DXF interface, for example:

GearDXF
- Free software for Windows
- Entries in inches or metric

InkScape has a gear tool. Not many option though and you need to import the SVG into QCad. But it works.

Thanks for that hint 0xdeadbeef. I wasn't aware of that.

I use GearDXF a lot. Actually, there is the option to create metric output. Just click on the "Standard" drop-down menu and you are presented with a choice of Standard (imperial) or Metric. Simple!
