ONSHAPE: DRAWING SHEETS

In Onshape, drawing sheets are essential for creating detailed technical drawings of both individual parts and assemblies. Here's how they are used for each:
Onshape Drawing Sheet for a Part:
When creating a drawing sheet for a part in Onshape, the designer starts by selecting the part they want to document. Onshape automatically generates the drawing view of the part, which displays the orthographic views (front, top, right, etc.) and isometric views (if required). The drawing sheet can then include dimensions, annotations, and other annotations to specify critical details, tolerances, and notes about the part. Section views, detail views, and auxiliary views may be added to provide additional insights into complex features. The title block, located at the bottom or elsewhere on the drawing sheet, contains crucial information like the part name, part number, revision history, scale, and author details. This title block ensures that essential details are readily available, and the drawing sheet serves as a comprehensive blueprint, enabling manufacturers to produce the part accurately and consistently.
Onshape Drawing Sheet for an Assembly:
Drawing sheets for assemblies in Onshape contain exploded views and Bill of Materials (BOM) tables. The exploded view depicts how the individual parts fit together to form the assembly. This view uses spaces and arrows to illustrate the assembly sequence, making it easy for assembly technicians to understand the spatial relationships. BOM tables provide a comprehensive list of all the components used in the assembly, including part numbers, descriptions, quantities, and other relevant information. The title block on the assembly drawing sheet includes details like the assembly name, drawing number, scale, units, and author's name. The title block ensures that crucial assembly information is readily accessible, and these assembly drawing sheets facilitate clear communication among team members, streamline the assembly process, and ensure that the correct parts are used during manufacturing.
In both cases, Onshape drawing sheets with their respective title blocks are powerful tools for documenting technical designs and facilitating efficient communication between designers, manufacturers, and other stakeholders. They are a vital part of the design process, ensuring accurate and consistent representation of parts and assemblies for successful product realization.

The video above goes over how to create a drawing sheet in Onshape for a part drawing with dimensioning and all the required views and line types shown.
Assembly Drawing Sheets
Assembly Drawing Sheets
The above video goes over how to set up a drawing sheet for an assembled part. This includes the full assembly as well as the exploded viiew shown on your drawing sheet. From there you are able to create your Bill Of Materials (BOM) table that would also appear on your drawing sheet.
Exploded Views
Exploded Views
An exploded view is a graphical representation used in technical drawings, particularly in assembly drawings, to illustrate how individual components fit together to form a complex assembly or product. In an exploded view, the parts of the assembly are separated and spaced apart, showing their relative positions and connections.
The purpose of an exploded view is to provide a clear and detailed understanding of the assembly process and the spatial relationships between the components. By visually "exploding" the parts away from each other, the viewer can easily see how the pieces fit together, identify assembly sequences, and visualize the various interactions and interfaces within the assembly.
Exploded views are commonly used in manufacturing, assembly instructions, user manuals, and product documentation. They are instrumental in guiding assembly technicians, maintenance personnel, and end-users to understand the structure and construction of complex products, ensuring successful assembly and usage.
BOM Tables
BOM Tables
A BOM (Bill of Materials) table is a tabular representation of the components or parts that make up an assembly or product. It provides a comprehensive list of all the individual items needed to build the assembly, including part numbers, descriptions, quantities, and other relevant information.
The BOM table is an essential part of technical documentation in engineering, manufacturing, and product design. It aids in procurement, inventory management, and assembly processes by providing a clear breakdown of the components required for the final product.
In assembly drawings, the BOM table is often placed next to the exploded view to give a complete overview of the assembly's constituent parts. Additionally, the BOM can include information about the material type, weight, cost, and supplier information, making it a valuable tool for project planning and cost estimation.
BOM tables are widely used in industries such as aerospace, automotive, electronics, and machinery manufacturing, ensuring accurate and efficient production while maintaining consistency in product data and documentation.
