- Is this a limitation of my graphics card?
I would think so, I'm using the default settings on a 2016 MacBook Pro using a Raedon Pro 455/ Intel HD Graphics 530.
TubroCAD has more tools. Comparing ViaCAD V10 to TurboCAD V10, ViaCAD is missing Rib, Edge Treatments, Pattern, GDT, Three more lights, and Animation. TurboCAD also has some added options within tools. The symbols library is missing all the 3D objects which to me is a requirement to use the architectural tools.
I ended up getting ViaCAD because I wanted the Power Pack Pro, Power Pack was available for TC but not the Pro version. The Pro version is now gone too taking the SubD to Nurb tool with it, but we did get a thread tool so that was a good trade.
