Surface Modeling and its applications… Class Title with Instructor Name. Edit from footer 2/25/2019

Pros of Surface Modeling Smaller file size Faster to render Simple geometry make-up: lines and polygons Google Sketchup with Ted Markson 2/25/2019

Cons of Surface Modeling Sometimes difficult for first-time modelers to pickup Simple geometry Non-mainstream Few Solid Modelers will interface with Surface Modelers Open Source community is fixing that Google Sketchup with Ted Markson 2/25/2019

New Model Establish a reference shape at the scale of your model Begin with the basic shapes of your design Seeing basic geometry lets your brain imagine the next step Google Sketchup with Ted Markson 2/25/2019

Model Containers Groups Components Do not have internal axes Act as single object. Double click to enter into group Components Have internal axes Act as single object. Double click to enter into component Changing one component will alter others Use for multiple of the same item design Google Sketchup with Ted Markson 2/25/2019

Subtractive Modeling Making complex shapes usually requires multiple geometry types Initially build more geometry than needed Erasing a line will remove the associated polygon Google Sketchup with Ted Markson 2/25/2019

Reference Modeling Use a corner or midpoint as known reference Draw line(s) from reference to get exact position needed Use arrow keys to snap movement or drawing to an axis Left key snaps to green axis Right key snaps to red axis Up key snaps to blue axis Hold the shift key to keep movement direction Google Sketchup with Ted Markson 2/25/2019
