Sometimes while working with construction lines, when you zoom out your drawing, you realize that the construction lines are not infinite as these should be. 

This could be annoying if you don't know the reason or the solution. 

What you have to do is to set Native draw to GDI mode. By default the Native draw mode is set to Redsdk. You can find Native draw under Options menu. Construction lines behave differently in GDI mode and Redsdk mode. Simply switch to GDI mode if you want to make end points visible for construction geometry.
