hello everyone, I drawn this model in SolidWorks and import it with three different extensions(STL,DXF,WRL) but it not working, just in stl extension but there is a problem with it there is a mesh on the model. I want to make a change in model using Block commands, so how can i do that and how can i make one of those extensions work??
