Notes /highlights from getting started with onshape talk by [[User:Matt]] as a part of [[K-Scale_Lecture_Circuit]][[File:Onshape notes.png|400px|thumb]]====== Starting with 2D Sketches ======Begin CAD designs with 2D sketches on planes, then extrude to create 3D shapes. ====== Dimensioning ======Proper dimensioning ensures accuracy, transforming sketches from blue (undefined) to black (fully defined).

===== Starting with 2D Sketches=Rollback Bar ======Allows reverting to previous steps in the design, useful for troubleshooting and understanding the sequence of operations.Begin CAD designs with 2D sketches on planes====== Using Constraints ======Applying constraints like coincident, perpendicular, and parallel defines precise relationships, then extrude making the design robust and easier to create 3D shapesmodify.

===== Dimensioning =Editing Sketches and Maintaining Integrity ======Changing a sketch updates all dependent features, but deleting a sketch can cause errors, emphasizing careful management of dependencies.

Proper dimensioning ensures accuracy====== Extruding Specific Shapes ======Select specific parts of a sketch to extrude, transforming sketches from blue (undefined) to black (fully defined)allowing for complex and controlled modeling.

===== Extrude Tool = Symmetric Extrusion ======Extrude a feature equally in both directions from a central plane for balanced and symmetrical parts.

Converts 2D sketches into 3D objects. Options like "new," "add," and "remove" are key for modifying shapes====== Multiple Parts Management ======Avoid creating multiple disconnected parts within a single part studio.Use assemblies

===== Rollback Bar= Boolean Operations ======Allows reverting to previous steps in the designCombine multiple parts into one using Boolean operations, useful though designing parts separately is often advised for troubleshooting clarity and understanding the sequence of operationssimplicity.

===== Using Constraints =Trim Tool ======The Trim tool helps clean up sketches by removing unwanted lines and intersections, aiding in creating complex shapes.

Applying constraints ====== Sequential Feature Order ======The order of features (like coincidentplanes, perpendicularsketches, and parallel defines precise relationships, making extrusions) in the design robust and easier to modifyfeature list is crucial. Moving a feature before its dependencies will cause errors.

===== Editing sketches and maintaining integrity = Fillet Tool ======Filleting edges not only improves aesthetics by rounding corners but also reduces stress concentrations, making parts stronger.Filleting can both add and remove material, depending on whether it’s applied to external or internal edges.

Changing ====== Creating Assemblies ======Assemblies allow you to bring multiple parts together and define their interactions.Parts can be fixed in space or mated using different types of mates (e.g., fasten, revolute).Fastened mates lock parts together in a sketch updates all dependent featuresspecific orientation, but deleting while revolute mates allow rotation around a sketch can cause errors, emphasizing careful management of dependenciesfixed axis.
