Challenge 4 : Concept Modelling of Alloy Wheel

• In this Autodesk Alias is a family of Computer-aided industrial design (CAID) software predominantly used in Automotive Design and Industrial Design for generating Class A surfaces using Bezier surface and NURBS modeling method.
• We are using this to Design to build the Surface Using the Alloy Wheel Traced from the given Image of Alloy Wheel.

4.Design Methodology / Approach:(To be explained with the help of Flowcharts only)

• Using Autodesk Alias 2020 Software, to build the surface using the curves model.
• Using New Page to create and Import that Canvas Image Front View, Top View, Side View, Back View.
• Alignment that Canvas Image size On Using Scale tool and Create New layers Option to seperate the layer.
• Using the Curve Tools in Palette Tool Box Option to New CV curve Tool to trace that model image.
• Using Circle and Ellipse in Keypoint curve Toolbox to drow the model.
• Using Detach Tool to separate the curves and surface area.
• Extend tool to using endpoint of surface to extending the surface and projecting area and trim it out unwanted area
• Using Symmetry to trace the curves plane.
• Using Blend Curve Create tool to creating the edge to perfect curve.
• Using spans and Degree to Adjust the curve line to trace the image model.
• And Using Surface option to create the shape for model by surface tool.
• Set Planar Tool to creating the surface to given the curve for alloy wheel.
• And Creating Curves line to trim that un wanted surface to remove it.
• Using Project / Intersect tool to projecting the curve line to the surface area.
• Using trim / Untrim Tool to using trimming area.
• Checking the surface continuity tool to whether the surface plane are in continuity line.
• Surface Option using that Skin Tool is using that controlling that curve are in continuity.
• Controlling the surfae area continuity by the Free Boundary, G0 Position, G1 Tangent, G2 Curvature, Implied Tangent, Implied Curvature, Tangent Angle.
• Using freefrom blend Tool to controlling the continuity by using position, curvature, Tangent.
• Using Align Tool to merge the both surface to continuity.
• Using Birail Gen 1 Surface Tool to creating surface area.
• And Using the Diagonstic shade to View the model of the image.

5.Description (Need to explain tools/ Features used while designing) along with the images of Part files.

• Curves (New CV Curve Tool) : Creating NURBS Curves in the scene by placing CVs.
• Keypoint Curve Tool : Using Circle and Ellipse to create two major axis point to create curves.
• Blend Curve Create Tool : Let You Create and Edit blend curves in the scene by placing location constraints
• Blend Curve Edit Tool : Let You Edit the Blend direction and continuity point.
• Extend : Curve Lines can be Extended to that paticular area.
• Detech Tool : Separate a curve or surface two or more object.
• Align Tool : Align a curves or surface edge to another curve or surface edge.
• Layers : Layers can be Assign that image to hide and mark and Pick to use.
• Degree And Spans : using this type to control that curves line to alinment that shape to trace that image.
• Surface Control : The Continuity Table displays one row for each boundary curve involved in the Square operation.
• Project : Project is that surface of the image can be project any curves in that surface area.
• Trim : Trim option is used to be remove unwanted surface area by projecting tool.
• Duplicate Curve Tool : Duplicate any curve that are picked when you click the tool and any curves while the tool is active.
• Surface Continuity Tool : Checks The positional, Tangent plane and curvature continuity between and inside surface.
• Diagonstic Shade : This tool can be giving that shape for texture and Colour for that model.

6.Upload a min of 4 screenshots of Model in the report. (For eg:-Front View, Side View, Isometric View and the Top View)

7.Conclusion :

• On Overall The technique of overbuilding surfaces, align surface with continuity check and then intersecting and trimming them can be used to create detailed design.
