The basis for the creation of high-quality catalogs is comprehensive training in the eCATALOG 3Dfindit software. The CADENAS modeling team can draw on more than 10 years of experience in this field and is therefore commissioned by customers to create the catalog as a service in about 90% of cases. The eCATALOG 3Dfindit software can also be purchased from the manufacturer itself in order to build the catalog. However, it is important to ensure that a targeted training course is planned and carried out at the beginning of the project, in which the customer's products are also individually addressed. Even after the training, further experience must be gained, because the rules recorded here (and generally in the CDM) apply equally to internal and external catalogs, insofar as publication on the CADENAS end media is planned.
