KoCAD 使用方法 | KOMORI 手册

从这里开始

Getting started: your first part in 4 stepsSketch, Smart Dimension (D), extrude with depth and a 2D drawing — the shortest path from a new part to the shop drawing.English
Install, sign in and work offlineWhere to download, how to sign in with your KOREOS account (ID/password, or KOREOS/Google in the browser), what works offline and how to see your PCs.English
A tour of the KoCAD windowTitle bar, menus, the 12-tab command ribbon, left and right panels, 3D view and status bar — where everything is.English
Mouse, trackpad and keyboard shortcutsOrbit, pan and zoom like SolidWorks, Fusion or Blender; factory shortcuts and how to change any of them.English

What to do when… (common problems)I can't sign in, the extrusion fails, the sketch turned red, 3D is slow, the AI is queued, the video won't export, the program closed.English

新功能Evaluate → Strength → Plate in bending (pressure): a thin rectangular plate under uniform out-of-plane pressure. You choose EVERY edge condition (supported, clamped or free — nothing is preselected) and enter E, ν with their source. Shows the maximum deflection, w/t (above 0.3 in red: outside small-deflection theory), moments, the surface bending stress, mesh convergence and a colour map; PDF PT/JP/EN. Acceptance: within 1 % of the Navier series and the Timoshenko table.
新功能Structural analysis: "+ Temperature change ΔT" applies a uniform ΔT to members (all, horizontal or vertical). The α of each material is then requested, with its source; without it nothing runs. A member fixed at both ends shows σ = E·α·ΔT. Static analysis only; a gradient through the section (bowing) is not treated.
新功能Tools → AI second opinion (optional): runs only when you ask. Before sending you see exactly which project facts go (features, material, KoCAD's checks and studies — no geometry, files or images) and choose the AI: KOIA/Cascata only with KOREOS Core access; otherwise the AI of your own key/subscription (explicit consent). Every AI receives the same rules. The reply is shown as SUGGESTIONS, each point with a source; points without a source are discarded, nothing is executed and text that reads like an approval is flagged. Editing the document marks the opinion as out of date.
