When start a perspective views, how to draw a line or circle?
Drawing tools will be introduced in Ignition 8.3 at the end of this year or early 2025.
You can import SVG files (which can be generated with Inkscape or similar). You can also use the Label component with fill and border and control the width, height and corner radius. (For a circle, set width = height and border radius = 50%.)
For examples of circles see How to make the circle icon as in image in perspective.
Got, Thank you!
