Easy for you to say. I create a drawing in Turbocad with nothing but a 3D solid box and chamfer does nothing. I cannot even copy and paste. I am running TurboCAD 2015, version 22.1 Deluxe 32 Bit on Windows XP. I have the same problem with 2016 with Windows 10. Obviously I am doing something wrong but the help is no help. It says that chamfering must be done by creating a surface on an angle and subtracting in Deluxe. If it is a simple task in DesignCAD why can't it be done in Deluxe? It looks like a case of forced upgrade.
I totally understand being a Design Cad user for many years.I agree with Henry if you're looking for more drawing aids.
Deluxe doesn't have a 3D chamfer or Fillet tool. You can chamfer and Fillet in 2D only.In Deluxe you can use the basic 3D tools, sweeps,Booleans,Revolve to accomplish many design tasks. It's more of an old school approach and with a little practice you can accomplish things almost
as quick as using an "automatic" tool.
Are you looking to do simple objects like in the attached image?
That was done in Deluxe 2016 32 bit,Lightworks.
As for your copy and paste problem I think that's a windows 10 issue.
