Hi,
It seems that the opacity is set to zero (making objects fully transparent) in FlexSim 2017 when using drawtext and not giving the opacity parameter. According to the documentation the opacity parameter is optional and before FlexSim 17 it behaved in such a way that the opacity was 1 if not given.
See the attached image. Drawtext also changes the opacity of the following draw3dtext and drawflattext commands. And drawflattext does not seem to be working as it should.
Thank you!
Kind regards,
Axel
