Hi Eric
Thanks for the text background change – that is much better

PS – In ClarisCAD you could select "Positive y is up" in the preferences so that your drawing co-ordinate system was properly Cartesian, rather than traditional "y-down" originally used in computer graphics and image processing (because of how images were stored in the framebuffer). That would perhaps be a useful addition?
For a lot of my drawings I set x,y = 0, 0 at what is commonly called the zero point in yacht design and construction. The x axis is the dwl (datum waterline) and the y-axis is the FP (forward perpendicular – where the forefoot crosses the dwl). So commonly my 0,0 is well over the the right hand side of the page, somewhat towards the bottom. That probably explains why zooms tend to got somewhere there unless I either select an object, or draw a small object to zoom on. But I haven't noticed zooms going accurately to my zero point – more just in that general direction?When you zoom with ⌘+ or ⌘-, the zoom is centered on selected object(s).
When the rulers are displayed, you can drag the cross at the upper left corner and put the origin where you want.
