Hi All,
I want to slightly change the behaviour of the text tool so it defaults to showing tags and other info (as opposed to the length of an edge).
I got quite far recreating it from scratch, but I think the native tool has some clever logic where it uses the camera position to determine the placement of the text.
Has anyone successfully implemented something similar before?
Thanks!
Ross
(1) All primitive geometry (edges and faces) should be untagged (using Layer0.)
(2) The native text (callout) tool uses “text always face camera”. When you use API methods to create text callouts, what specific problems do you have. (Please show screen snips or post code.)
Hi Dan,
Thanks for the very fast reply. I’ve uploaded a screenshot that hopefully shows the issue.
The native tool (blue mark up) cleverly infers an insertion point from the camera position that makes sense.
My tool (green mark up) places it the text really far away.
Full code is below. Thanks! Ross

Well, my first thought is that you are transforming the @start_point but not transforming the end_point used to create the leader vector.
Secondly, I would get the @mouse_ip for the second click within the onKeyDown callback. (Just me I suppose.)
