Mastering AutoCAD OSNAP and OSNAP Overrides

When working in AutoCAD, precision is everything. Whether you’re drafting architectural plans, mechanical parts or electrical layouts, being able to accurately snap to specific points in your drawing is essential. That’s where Object Snaps (OSNAP) and OSNAP Overrides come into play.

In this blog we’ll explore what OSNAP is, how to use it effectively and the different between persistent OSNAP settings and temporary overrides.

What is OSNAP in AutoCAD?

OSNAP (Object Snap) is a drafting tool that allows you to snap to exact geometric points on objects, such as endpoints, midpoints, centres, intersections and more. It ensures your cursor locks precisely onto key locations, eliminating guesswork and increasing accuracy.

Let’s have a look how:

• Open AutoCAD. At the bottom of your screen, first check OSNAP is active on your status bar as shown in the below image.

• If it’s not on, click the 3 lines at the bottom right of your screen, and toggle 2D Object Snap ON.

• At the bottom of your screen, on the status bar, click the dropdown arrow as below. Here we will select what OSNAPS we want to set as default when we are in a command and hover over the geometry.

• Once OSNAP is active, AutoCAD will automatically snap to the enabled object snap points whenever your hover over them. Having too many OSNAPS active can slow down performance and make it difficult to snap to the correct point.

• You can temporarily override these settings. When in a draw command, hold SHIFT and RIGHT CLICK and select the OSNAP from the pop-up list. This will temporarily override your OSNAP settings. After this has been selected and used, it will revert to the settings selected in the OSNAP settings.

Mastering OSNAP and OSNAP Overrides in AutoCAD can greatly enhance your drafting accuracy, speed and overall efficiency. Whether you’re just starting out or have years of experience, knowing how and when to use these snapping tools helps ensure cleaner, more precise drawings every time. OSNAP isn’t limited to drawing commands. It also plays a key role in maintaining accuracy when placing text, dimensions, using modify tools and more.
