I chose to purchase Alibre design as my cad of choice. With that said my maintenance expired in June and I made the decision not to update as I only use it sporadically in my woodworking hobby. It fulfills my need fully incorporating designs using assembly. My question pertains to any bugs that may be discovered in version 29. Will those of us who are happy with version 29 and have no need at the time for any additional features like weldements be provided with general bug fixes. If any additional features in the future happen to be available I understand I may again update to add to my license. Jerry
