actually, my sketchup pro 2017 (v17.0.18899) was working properly, without any problem!
I just Uninstall and reinstall it again (v17.2.2555) and this problem appeared!.
I read and do many many things such as checking my local and language option but everything was ok! so last night just uninstall the sketchup (v17.2.2555) and install the version ([highlight=#ffff80:2wtf7s7m]v17.0.18899[/highlight:2wtf7s7m]), and without any change to my regional and language Option everything is fine.
