# Version 363

## Layout Updates

### Truss Envelope Insertion

Truss envelope ends will no longer be automatically calculated during insertion after you pick specific end points. Use the Recalculate buttons when you want the ends adjusted automatically, or adjust them after inserting the truss envelope using trim/extend or choosing new end points.

### Control Plane Visibility While Cutting Truss Envelopes

You can now adjust the visibility of roof and ceiling planes while adding top and bottom cuts to truss envelopes. Changes you've made to your visibility settings before you start cutting will also be respected.

### Scale PDF Underlays Using Ratio

When you import [PDF Underlays](https://docs.paragontruss.com/layout/layout-overview-1/tools-and-features#pdf-underlay), you can enter the scale as a ratio.

### Focus Camera to Selected Item(s)

[**Focus Camera**](https://docs.paragontruss.com/layout/layout-overview-1/interface-overview/layout-options-toolbar/view-and-link-options) (`Ctrl + .`) will now focus to all selected objects.

## Design Updates

### Prefer using one plate on short stacks

Short top chord sliders like the ones at the ends of many floor trusses will get a single plate more often.

### Avoid Upgrading Stacked Members Unnecessarily

Sometimes both members of a chord stack would be upgraded when only one of them needed to be, but they are now considered independently in those cases.

## Bug Fixes

* Fixed the initial zoom behavior in a 3D view to ensure all layout objects are visible
* Fixed an issue with panning layouts in 3D that could cause unexpected movement
* Fixed an issue with computing overhangs on roof planes that cut against an object in another level
* Many TRE files that could not be imported or could not be edited after importing are now partially or fully supported
