Hi,
I am using WorldDraw() in jig to draw a block reference as I move the cusror(something similar to preview cursor). But I observe there is too much flickering even if I have the point comparison to return SamplerStatus.NoChange in the Sampler().
Could someone help me with this.
It is somewhat hardware (video card of the computer) related, depending on whether hardware acceleration is on or off (usually it is on). There are 2 system veriables that you can try to change their value to improve or worsen the said flickering effect: DRAGP1 and DRAGP2. When hardware Acceleration is on, you could try to reduce DRAGP1 value from default 5000 (if my memory serves me correct, because I had the same issue with my DrawJig with my old, low-end computer back a few years ago. You can try both reducing or increasing the value, of course). But it seems computer/hardware related, so you may not want to make the aproach of changing DRAGP1/2 value into your code as hard-coded solution.
It seems this only happens to Jigs derived from DrawJig. Personally, I prefer using TransientGraphics in conjunction with Editor.PointMinitor handler and Editor.GetXXX() over DrawJig.
