How is a bag made?

The Bag Pattern Making and Prototyping Course at the prestigious Arsutoria School in Milan teaches the art of bag making in its eight-week course.  Supported by a team of professors with many years of technical experience in the sector, students coming from around the world are immediately immersed in a work environment that replicates the experience of working in a leather goods workshop.  Here, it is possible to learn about the raw materials and components used in the manufacturing of bags, as well as all the phases of bag pattern making, using instruments and machines that employ the sector’s latest state-of-the-art technology.

One of the most important parts of the course takes place in the CAD classroom, where students learn to design and develop their bag projects using the technology offered up by the Comelz Caligola CAD system.  Overseeing the works of the students is Simone Paolacci, educational trainer for Comelz, the Vigevano company that has made its innovative software available to the school and its students.  We ask him:  how does the Design Module work in relation to the CAD?

“The students enter a critical phase of the course:  they must develop their project on a CAD platform and then learn to use the tools of Caligola software in order to design their bags.  The parameters set by them in this phase will be decisive to the next step of prototyping:  systems like Caligola connect the creative phase to the manufacturing one, and the project to machines for production”.

Therefore, it’s not just a simple matter of designing a bag…

“It’s the development of an essential skill needed to comply with company procedures.  An instrument like Caligola allows for the optimization of all phases in design:  first of all, it is easy and intuitive to use, since it allows every user to customize the settings of the instruments and functions to suit their own individual needs, thus making it easier for beginners to learn, while speeding up the work of expert users.  Caligola also allows a brand new pattern to be developed, or to work on a pattern that has been imported, for example, by a scanner, as well as make any changes, with subsequent automatic corrections made by CAD to the entire project.  Moreover and just as important, besides communicating with production, Caligola can also be connected to the management system for datasheets and calculating consumption”.

It is a genuinely invaluable instrument for the pattern maker:  what has made Caligola so effective?

“Caligola was conceived at the beginning of the Nineties and has almost thirty years of constant innovation behind it resulting also and, above all, from the feedback provided by users and students in the training courses.  For this reason, today, this instrument has been honed to perfection:  it allows every function of pattern making to be carried out, thanks to instruments that are easy to use and intuitive.  Additionally, today, on Caligola there are also a number of unique graphic functions that can be used, like overlapping or transparencies, multicolour common lines, antialias filtering for high quality representation, automatic labels, piece creation facilitated by hiding of non-related entities, etc.; essential instruments for passing through the design all the information necessary to the subsequent phase of production”.

While Simone Paolacci explains the features of Caligola, students continue to focus on the development of their bag designs, and while observing them, I can’t help but think that one day they will be the ones managing their own companies, or working to develop collections for leading leather goods designer labels.  Caligola will probably once again be an important ally in this context.  “Caligola is highly compatible and easy to update:  it can be used on Windows, Mac OS X, and Linux and is open to every CAD/CAM system, it respects Assomac standards, exports data and patterns in different formats (CMZ, DXF, PDF, CSV, XML, HPGL) for printers, plotters, cutting devices, and obviously, it directly communicates via internet with the Comelz support server.  Basically, it is super-compatible.  Simone Paolacci concludes, “Another advantage of the Caligola system is that the end user license of the purchased version is irrevocable and transferrable to anybody at any time:  this means that I can put my program on a USB key, easily bring it to my customers, and make the changes that they ask of me in person, without having to go through the bothersome exchange of e-mails that slows down the entire process and creates disruptions”.

In other words, when an innovative technology is at the service of creativity, there are no limits to the imagination and the ability to realize important projects.  Comelz technology makes all the difference also in this context.
