Course Duration: 40 hours (or whatever your needs are) 

Tuition: $2,500 USD or contact Design-Engine at 312.226.8339 for an onsite estimate

Overview: This workshop is an advanced Surfacing intensive. The course curriculum is flexible, and can cover any of the more advanced techniques and workflow for surface modeling. Top-down surfacing, with respect to co-injected plastics, Surface Edit in Creo style, Creo Aircraft Surfacing, freestyle Sub’d surfacing or all the new Creo surfacing additions. Most commonly, this course covers all of the Design-Engine Creo Surfacing classes that are not covered in the typical Design Engine Week One surfacing class.  Creo Surfacing Level 5 Creating Parametric Surfaces from IGES geoetry, Creo Surface Edit in Style Level 8, Creo Subdivisional modeling Level 10 and Creo Import Data Doctor Level 11. This course also goes deep into managing co-injected plastic and equation, trajpar & evalgraph functions for driving cross sectional area. We also reserve a portion of  classroom time for individual projects if necessary. Usually there are less than two or three people in this workshop so instructor/student ratio is ideal. This class can be customized to include any of our workshops.

Prerequisite: Participants in this course must have taken the Design Engine Creo Surfacing: Week One and have used surfaces for at least one year after completing that course.

Audience: This workshop is an intense one-week course. This class is imperative for product designers who are pushing the new Creo surfacing tools, and product designers who lead the design teams of major manufactures.

Note: This course is usually customized to focus on the participant’s learning wishes (last day) and company-specific projects. Bring example work or problematic models on flash drives for in-context discussions for work during and/or on the last day of class. We supplement this training with Alias Auto Studio style techniques utilized in the automotive industry so some comparisons will be made in this class.

Brief:

This course is a serious advance on the Design-Engine  Creo Surfacing: Week One workshop. This Creo training course is developed for specific seasoned  users who previously took the Design Engine one week surfacing intensive and want to push their proficiency learning potential with Creo Surface modeling in just one week. We help you learn specific workflow techniques using Creo not read to you from an exercise. In this course, we help design engineers and industrial designers discover techniques for leveraging Creo Surfacing in ways other more experienced users may not have discovered plus practice methodologies for making changes quickly to set them up for pushing past expert status. As with all Design-Engine classes, participants keep the training material login and password for life.
