Know when unwanted layers creep into your drawing with layer notification

Layers are a big issue when it comes to maintaining drawing standards. Where you work, you may have lots of rules about which layers your drawings can have.

Xrefs can be a problem for drawing standards, because when you attach an xref, its layers come along for the ride. This is especially an issue when […]

Batch check multiple AutoCAD drawings against a standards file

In a previous post, “Use a Standards file to bring an AutoCAD drawing into line,” I explained how to check a drawing for certain standards, such as layers. This process is important for maintaining drawing standards where you work.

But suppose you want to check standards for many drawings at once? You can, using the […]

Autodesk 360 is a new cloud-based workflow for AutoCAD drawings

Autodesk 360 is a cloud-based online service is used primarily for storing and reviewing drawing files on the go. There is also AutoCAD WS, which is a web app that lets you edit DWG files online, including on mobile devices. In this post, I’ll focus on Autodesk 360.

Use a Standards file to bring an AutoCAD drawing into line

How to break walls to insert a door

In an architectural drawing, you often need to break walls to insert a door. There are many ways to do this, but here is one way:

Let’s assume that you have a simple wall 4 inches thick. You want to insert a door that is 28 inches wide. You can easily translate these numbers into […]

Combine or subtract 2D shapes with the REGION command to create custom shapes

Sometimes you need to create a 2D profile that is a combination of the basic geometrical shapes that AutoCAD creates. While you might be able to use the PLINE command to create what you want, an easier way might be to combine or subtract simpler shapes.

For example, let’s say that you want to create […]

A different way to create an ellipse or oval
