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).
====== Extrude Tool ======
Converts 2D sketches into 3D objects. Options like "new," "add," and "remove" are key for modifying shapes.
====== Rollback Bar======
Allows reverting to previous steps in the design, useful for troubleshooting and understanding the sequence of operations.
====== Using Constraints ======Applying constraints like coincident, perpendicular, and parallel defines precise relationships, making the design robust and easier to modify. ====== Editing Sketches and Maintaining Integrity ======Changing a sketch updates all dependent features, but deleting a sketch can cause errors, emphasizing careful management of dependencies. ====== Extruding Specific Shapes ======Select specific parts of a sketch to extrude, allowing for complex and controlled modeling.
Applying constraints like coincident, perpendicular, ====== Symmetric Extrusion ======Extrude a feature equally in both directions from a central plane for balanced and parallel defines precise relationships, making the design robust and easier to modifysymmetrical parts.
===== Editing sketches and maintaining integrity =Multiple Parts Management ======Avoid creating multiple disconnected parts within a single part studio. Use assemblies
Changing a sketch updates all dependent features, but deleting a sketch ====== Extruding Closed Shapes ======Only closed shapes can cause errors, emphasizing careful management of dependenciesbe extruded. Converting lines to construction lines helps define closed shapes without affecting the extrusion process.
===== Extruding Specific Shapes =Boolean Operations ======Combine multiple parts into one using Boolean operations, though designing parts separately is often advised for clarity and simplicity.
Select specific parts of a sketch to extrude====== Trim Tool ======The Trim tool helps clean up sketches by removing unwanted lines and intersections, allowing for aiding in creating complex and controlled modelingshapes.
===== Symmetric Extrusion =Sequential Feature Order ======The order of features (like planes, sketches, and extrusions) in the feature list is crucial. Moving a feature before its dependencies will cause errors.
Extrude a feature equally ====== Advanced Sketch Relationships ======Besides basic dimensions, you can define angles and even perform arithmetic operations within dimensioning.This includes converting units directly in both directions from a central plane for balanced and symmetrical partsthe dimension input (e.g., adding inches to millimeters).
===== Multiple Parts Management =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.
Avoid creating ====== Creating Assemblies ======Assemblies allow you to bring multiple disconnected parts within a single part studiotogether and define their interactions.Parts can be fixed in space or mated using different types of mates (e.g., fasten, revolute). Use assemblies for combining multiple Fastened mates lock partstogether in a specific orientation, while revolute mates allow rotation around a fixed axis.
