Course Duration: 16 hours
Tuition: $1,500 USD
[accordion autoclose=false openfirst=true clicktoclose=true]
[accordion-item title=”Overview +” state=open]Discuss different surfacing styles and techniques using air forms as examples. Work with curves from points. Learn to create and modify Conics, Spines, & Curves with respect to air forms. Learn to use critical math surfaces with confidence in this workshop.[/accordion-item]
[accordion-item title=”Prerequisite +” state=closed]This workshop is for designers and engineers who have at least taken the Design Engine One Week Surfacing Intensive. This course is intended to aid participants to master building critical air forms. Prior Pro/E surfacing with Pro/Surface and ISDX is necessary. No prior Aircraft experience is necessary.[/accordion-item]

- Create wing fillets and wing tips and discuss concerns with respect to aerodynamics.
- Utilize new skill sets to smooth out solid material from problem areas and to force rounds in transition areas.
- Build more robust curves and surfaces.
- Learn a workflow to use offset surfaces instead of the shell feature command with respect to carbon fiber lay-up techniques.
- Learn about striation or flow of surface.
- Manage concavity and discuss terminology with examples in Pro/E that aircraft designers utilize with respect to bifurcation tubes and inlet ducts.
- Learn inherent issues and problems with 3-part boundaries.
- Discuss modeling technique for creating Nacelles and inlet areas for power plants.
- Learn to use critical math surfaces with confidence.
- Learn to utilize copy geometry to make for clearance of critical internal features.
