Hello, 
   	  
   	I'm using an version 2019 of the software and I'm facing a problem. The nodes only appears on the screen when they are selected. This is a problem, because when I create a node, it get lost on the workspace, invisible on the screen (When I was creating the node, I took care to click 'fit model'). 
   	  
   	I realized the folowing test: I create two nodes (000) and (010), and selected 'fit model'. After that I selected 'lines'>'linear nodes'>'node list' and holding Shift I made a selection of all the workspace. Doing that the nodes appeard in grey collor on the screen. 
   	  
   	Somebody can help me with this problem, please? 
   	  
   	Thanks in advance, 
   	Renato.
