Last week’s Adobe Illustrator drawing was a replacement for the slide I use to describe the role of skin in thermoregulation. I needed a diagram showing a hair shaft for insulation, a nerve ending for detection of thermal changes, blood vessels that dilate to release heat and a sweat gland for heat loss via evaporation of sweat.
I thought drawing a sweat gland would be easy; draw a fat squiggly line and then make it into a solid object with a line around it (object-path-outline stroke). But, as you can see on the left, this didn’t work quite how I had intended since it outlines the outer boundary of the squiggle rather than the squiggle itself. So I had to cut my next squiggle up then outline the pieces and layer them so that the ends weren’t visible. Sorted.
