Going on from https://forum.bricsys.com/discussion/29072
, to the related subject of tracking lines with the Dimension (measure) tool, and locking same, could this not be modified to act same as the yellow dashed general cursor tracking line?
First, when using Dimension, could the tracking line be the same dashed yelow line, which is equally easily locked to a Polar vector with a single dab on Shift?
Next, I find the locking much easier when the dashed yellow cursor tracking line shows, when using Move for example, than when Dimension's solid tracking line shows.
In both cases, with my usual Entity Snap settings, the tooltip usually says Endpoint, even when I'm on a Polar vector. Only with much jigging around can I sometimes get the tooltip to say Polar.
With Move's dashed yellow line this doesn't matter - it locks easily to Polar.
But with Dimension's solid tracking line, it will only reliably lock to Polar when the tooltip says Polar (which is rarely, and with difficulty) - it usually won't lock when the tooltip says Endpoint (but occasionally will), even if I'm on the Polar vector.
If it does lock and I unlock, it won't ever re-lock with Shift - have to re-start the Dimension tool.
The tracking and locking with Dimension seems unreliable and tricky, compared to same with the yellow dashed general cursor tracking line.
