Proteus 8 Professional 8.3 SP1 Build 19777 | 258.38 MB
Proteus 8.3 was largely based around re-working the way in which we transition from PCB Layout (ECAD) through to mechanical layout (MCAD). Over the last few years the STEP file format has become the de-facto standard for data exchange and we have therefore implemented full support in the Version 8.3 release.
