I'm trying to learn Affinity Designer 2 (AD2) from scratch. I want to draw straight lines on a Dimetric Grid to start learning how to draw simple objects in AD2 before getting more complicated.
I select the Pen tool, select Line mode, and start to draw. I'm trying to draw a cube in 2D on a Dimetric grid.
I have Snap to node and Snap to Grid on, and the grid showing.
I have Preserve selection (don't really know what that does) on, and Add to Curves on. Join was on, I accidentally turned it off, and now it won't come on again.
I get part way through drawing a cube, and suddenly each new line I draw deletes (or perhaps just hides?) a previous one.
All that's left is the outside of the drawing. All the interior lines have disappeared.
And now only the last line I drew has highlighted nodes. The other lines in the overall outline have no visible nodes.
How can I stop this happening?
I've searched the forum for Pen Tool and iPad, and get no results.
Help, please. Until I figure this out, I can't see how to use this powerful tool to make quick sketches of woodworking objects.
PS. I have read Quick Start and am now trying the Help, to understand lines and curves.
