Drawing Document and Orthographic Views
To first step to create a drawing in Solid Works is to start a new file and choose a drawing format. Select the “A4 Landscape” format which is 11 by 8.5 inches. Next, insert a model (part or assembly) into the drawing file. Solid Works allows you to place the base view and projected views quite easily. The Command Manager gives you quick access to the “Drawing” tools, “Sketch” tools, and “Annotation” tools. When placing a view you can select the scale if the default scale does not appear to be right. Just like part or assembly templates, we can define our preferences in a new drawing template. You can set a number of System Options to suit your needs.
System Options and Document Options
System options are settings that apply to all the drawings. Document options apply to each document and can be placed in a template. Here is some of preferences for this class:
• Units to be mm
• Standard to be ANSI
• Hidden lines are to be invisible
• Dimensions appear without parentheses or boxes around them
• Tangent edges are to be invisible
Adding model dimensions
Add model dimensions manually. Model dimensions can be imported but do them manually for this assignment. The system can add Hole-Wizard specifications automatically.
Standard practice in Dimensioning
Just because two lines “appear” to be equal length, or they are “obviously” part of a symmetrical figure, is not sufficient reason to leave them un-dimensioned. There are some default standard agreements you can use to dimension your drawing sufficiently. Here are some of the important ones:
• Lines that appear to be collinear are considered collinear unless other dimensions exclude this possibility.
• Lines that appear to be at right angles are considered at right angles unless other dimensions exclude this possibility.
• Lines that appear to be parallel are considered parallel unless other dimensions exclude this possibility.
• One of the features that repeat on a view can have their dimensions preceded by nX to indicate that the dimension applies to all features when there is no ambiguity.
Beyond this, nothing else should be considered default interpretation. If you leave features un-dimensioned, you have to accept the results whatever they may be. Options to add more views include:
• Section Views
• 3D Views
• Detailed views
• Cut out views
• Drawing Sheets
3D views like isometric views can be added by inserting a base view, selecting the part through browser, and inserting an isometric view. All the part or assembly views generated are placed in a drawing sheet. We can insert more drawing sheets. These drawing sheets are independent and can have different parts and formats.
Hidden Line Visibility
The standard practice regarding the visibility of the hidden lines is as follows:
In general, views should be chosen that show features with most visible lines as much as possible. After this has been done, hidden lines should be used whenever necessary to make the drawing clear. When not needed for clarity, they should be omitted.
To turn the hidden line visibility of certain features, click on the feature from the drawing browser in the view of interest and from the Right Click menu select the “Show/Hide” option.
Spindle Drawing Assignment
Create a model of the part using the given dimensions. Then create a drawing and add dimensions such that it exactly matches the drawing that follows. Add custom sheet format to the drawing for the Spindle with fields exactly matching the drawing.
