Is AllyCAD similar to ChoiceCAD / TrueCAD?
It is identical except that it has minor interface changes, substantial changes in functionality and includes our sought after toolkits. At one stage all three products were identical except in branding. Since the decision to move to one brand name no updates have been provided for ChoiceCAD or TrueCAD, which means that they are now significantly lacking in the features that AllyCAD provides.
