Hi! 🚀

Take your 2D drawings up a notch with centerline geometries: _2-point and 2-line centerlines_. All you have to do is select points and lines, and the app will mark up your technical drawings.

For more tips and tricks, drop by the [Manual](https://support.shapr3d.com/hc/en-us/articles/4403979479058). And make sure to stay tuned for future releases, because we’re planning to unleash more geometry tools for 2D drawings, _including 3-point circular centerline and center mark._

But that’s not all! Here’s a roundup of the other fixes in this release:

- You can export STL files for 3D printing using either binary or ASCII output format without a hitch.
- The **Area Selection** tool will no longer be triggered when you long-click the **Copy** , **Lock** , or **Scale** badge.
- Construction axes will be highlighted when you hover over them with the mouse or trackpad
- Numbers and units in dimension labels won’t be cut off anymore.
- Any selected body’s measurement details will accurately reflect any finalized changes.

Download and install [version 4.8](https://apps.apple.com/hu/app/shapr-3d-cad-modeling/id1091675654) to give these boosts a spin!
