So you want a job using AutoCAD? Fantastic. Here is a list of specific skills that you must know in order to work as a professional AutoCAD user. I’m assuming you know the AutoCAD basics like how to draw lines, circles, and arcs and that you know the difference between a polyline and a spline. That's not enough in this job market anymore. So here's a few more must-have AutoCAD skills to get your dream job.
I know, it sounds obvious, but it is worth stressing. AutoCAD will do a lot of the drawing work for you but you still need to know how to draw.
Layer Management Skills
AutoCAD manages its data with layers. Layers group similar objects like text, dimensions, construction lines, doors, windows, pavement, hatch patterns, labels, or whatever it is you are drawing. Every company will have a specific way to manage their layers in order to ensure quality control and to provide an environment where everyone can work together. Layers control the color, linetype, line weight, and printability of everything in your file. There is a right way and a wrong way to manage your drawings layers. Make sure you understand how to use them in a drawing environment.
Understand how to use Xrefs Properly
Xrefs are referenced files. Typically a project will have a base file. This is the main file that contains the linework that makes up the bulk of your project’s design. Once that is created, other files, drawing files, will be created that will reference your base file. These secondary files will be the ones that contain your drawing’s titleblock, dimensions, notes, and any other annotation. You need to know what to do when your project goes through a revision and what parts of your project belong in which base file. The company you will be working for should have a system in place to manage what goes in which xref file.
Styles are everything. Styles control the visual display of AutoCAD annotations like text, dimensions, tables, and leaders. A style will control which font is used, the height of the text, the dimension arrow head, if there is even an arrow head, what scale the annotation is used in and what color it will be. Understand that you can over do it with too many styles.
When and When Not to use Paper Space
Simply put, model space contains your model, the line work. If you are making a 3D model or simply drawing in 2D, the linework goes in model space. Paper space is where you create your drawing. Put your title block there and use viewports to view your model from model space. Create details or sections in paper space, or draw them in model space and use a viewport to see the model. It’s up to you to decide which method works best and that can vary depending on the situation. Knowing the difference is key.
Viewports are windows in paper space that provide a means of displaying your model space contents. Viewports control drawing view and scale. They also allow you to create multiple views in one drawing of which each has its own set of layer controls. AutoCAD users will need to know how to manipulate layers in viewports with viewport overrides in order to display linework differently as needed. They allow you to display the exact same linework in different ways on the same sheet. You can show linework as existing in one viewport but as proposed linework in another without changing the model or the base file.
This one can be difficult for many new CAD users. While learning to use AutoCAD we rarely have to use more than a few files for our projects. In the real world though we can use dozens of files for one drawing. AutoCAD users need to be able to know which file to use where and why. You also need to know how to archive files when there are revisions. Sending files to a client can also be a chore so make sure you understand how to use etransmit.
If you don’t know how to implement Sheet Sets into a project stop what you are doing and watch this video on Novedge that I made discussing Sheet Sets.
The Sheet Set manager provides tools for managing the files in your project. It can create new files from a template automatically, print all or specific drawings from your project, manage drawing sets, create subfolders for file management. It provides a means for sharing project specific data and can simplify drawing naming and numbering procedures. Sheet Sets also make collaboration easier.
