# v0.5.0 — Hole-pitch measuring, 3-point section planes and STEP export
|
||
|
||
## ✨ New features
|
||
|
||
**Measure hole-to-hole pitch in two clicks — snap to circle centers**
|
||
* Point / Distance / Align picks now **snap to the center of a circular edge** when you click near
|
||
a hole or a round boss — measure connector pin pitch by simply clicking two hole rims.
|
||
* Vertex snapping still works; whichever feature is closest to your click wins.
|
||
|
||
**Keyboard shortcuts and Esc**
|
||
* Measure modes now have hotkeys: **P** point, **D** distance, **E** edge, **F** face, **C** circle,
|
||
**A** angle, **M** face-to-face. Press the same key again to go back to browsing.
|
||
* **Esc** cancels an in-progress multi-step measurement first (keeping the mode), then exits the
|
||
mode, then closes the manipulator — no more re-clicking toolbar buttons after a mis-pick.
|
||
|
||
**Standard views and orthographic projection**
|
||
* One-click **Iso / Front / Top / Right** view buttons (Z-up, mechanical convention).
|
||
* New **orthographic ⇄ perspective** toggle — check dimensions without perspective distortion.
|
||
The 3-axis manipulator stays perfectly aligned in both projections.
|
||
|
||
**Assembly tree: search, isolate, volume**
|
||
* A **search box** above the tree filters nodes by name (ancestors and children of a match stay
|
||
visible, branches auto-expand) — find one part in a hundred instantly.
|
||
* Right-click any node: **Isolate** (show only this node), **Invert visibility**, **Show all**.
|
||
* Right-click **Volume / centroid**: closed solids get mesh-based volume, a centroid marker in the
|
||
view, and overall L×W×H. Node tooltips now show each part's bounding size too.
|
||
|
||
**Cut along any plane — 3-point section + numeric position**
|
||
* The section axis picker gains a **"3-pt"** option: click three points on the model to define an
|
||
arbitrary cutting plane, then sweep it with the position slider as usual.
|
||
* The position value is now also an **editable number field** (0–100 %).
|
||
|
||
**Interference check across 3+ files**
|
||
* The check now accepts **two or more** visible files and tests **every pair**, reporting each
|
||
pair's result (intersection lines or minimum gap) plus a summary of how many pairs collide.
|
||
|
||
**Hand off your alignment — export the scene as STEP**
|
||
* New **📤 STEP** button writes all visible parts **at their current aligned positions** into a
|
||
brand-new STEP file — mate connectors in STPViewer, then hand the assembly to any CAD.
|
||
Original files are never modified.
|
||
|
||
**Quality of life**
|
||
* Window size/position, mm ⇄ inch choice and the **last 10 opened files** (▾ next to Import) are
|
||
remembered between sessions.
|
||
* The tree and measurement panels are now **resizable** with drag splitters.
