Open JWW files on a Mac
Files you can open
- .jww: Jw_cad drawings. Tested with drawings saved in Jw_cad v10 and 8.25a.
- .jws (shapes) and .jwc (the older format)
- .dxf: opens in the DXF to JWW conversion view (see Convert DXF to JWW).
How to open a drawing
- Double-click a .jww file in Finder. If another app opens it, choose Settings… > General and click Make JWW Bridge the Default App for .jww.
- Drop a drawing on the start screen.
- Choose File > Open… (⌘O), or pick one under Recent Files on the start screen.
While a large drawing loads, you see “Opening “file name”…”.
Tabs
Drawings open as tabs in one window. Press ⌘T for a new tab with the start screen. Drag a tab out of the window to give it its own window.
The next time you open JWW Bridge, the drawings you had open come back. To start with the start screen instead, change At Launch in Settings… > General.
If a drawing you have open is saved again in Jw_cad or another app, JWW Bridge reloads it and keeps your zoom and layer settings.
Change what you see
- Layers: click a layer in the list on the left to show or hide it. Right-click for Show Only This Layer and Show All Layers.
- View menu: grid, construction lines, temporary points, markup, show hidden layers faintly, thin lines, fine dots and spacing, and the background (white, black, or matching the appearance).
- Drawing Info: the right side shows the paper, scale, text encoding, element counts and more.
Search text
Choose Edit > Find in Drawing… (⌘F) to find room names and labels. Press ⌘G for the next result and ⇧⌘G for the previous one. You can choose whether to search hidden layers too.
Preview in Finder (Quick Look)
Select a .jww file in Finder and press the Space bar to see the drawing without opening JWW Bridge. File icons in Finder show the drawing too.
Text search, the background switch, Quick Look and icon previews are available during the free trial and after purchase (see Free trial and purchase).
