Model viewer¶

The controls, toolbar buttons, panels and sidebar tabs of Bramble's 3D model viewer. It opens full screen, and shows a simplified (decimated) version of each Part's mesh, so it loads faster than the uploaded file.

Where it opens¶

The viewer from View all assemblies and View Run Model is the Run model viewer. View Processed Geometry shows the geometry after kinematics have been applied, as it goes to the mesher. It's only available once processing has succeeded.

While it loads, a progress bar reads "Downloading: <description> <n> of <m> file(s)".

View all assemblies is disabled, with a tooltip, when:

• "You do not have permission to load Part files."
• "Accessing this model is not allowed."
• "Template case has not finished loading."
• "assemblies are empty."

Layout¶

• The sidebar is on the left. The arrow button on its edge collapses and expands it.
• The 3D scene is on the right, on a white background.
• The toolbar is in the top bar, next to the close (×) button.
• Toolbar buttons open floating panels. Drag a panel by its title bar. − / + minimises or restores it, and × closes it.

Mouse controls¶

• Isolate and hide work on Parts or on zones, depending on the Parts / Zones option in the sidebar.
• Hidden and clipped-away geometry can't be picked.
• There are no keyboard shortcuts. The only keys are Shift, Ctrl and Cmd with a click, and Alt while measuring.
• To reverse the scroll-wheel zoom, tick Invert Postpro Zoom Direction in user settings. Despite its name, it also affects the model viewer. Reopen the viewer after changing it.

Toolbar¶

The View Setup viewer has no toolbar or sidebar. See Kinematic Setup viewer.

Panels¶

View Angle¶

Each view fits the whole model and resets the rotation centre to its centre. For the axes, see coordinate system and units.

Model¶

Measurement¶

1. In the Model panel, tick Enable Measurement. Orbit and pan switch off, and the cursor becomes a crosshair.
2. Click a point on the model to place point A.
3. Click a second point for point B. A line joins them, labelled with the distance and its components along the global axes, in whole mm, for example 1234 (1200, 50, 280) mm.
4. Click again to clear it, then click to start a new measurement.
5. Hold Alt to orbit or pan without placing points.
6. Untick Enable Measurement to remove the measurement and turn orbiting back on.

There's one measurement at a time.

Clipping¶

• You can enable several planes at once. Geometry on the cut side of any enabled plane is removed.
• Clipping applies to the model surfaces only, not to Kinematic Setup or Template Case overlays.

Camera¶

Run model viewer only, and hidden for Restricted Users. Use it to view, edit and create the postpro cameras in a camera set.

While the panel is open, the scene is framed at the postpro images' 16:9 aspect ratio, with a Postpro View caption.

Deltas¶

Run model viewer only. It shows Baseline: (the Run's baseline, or (Not Available)). Choose a Programme, Project and Runs to compare against:

• Parts added relative to that Run are shown green.
• Parts removed relative to that Run are shown red, and listed under Removed Parts in the sidebar.

Kinematics¶

A toggle in the Run model and Processed geometry viewers, shown when the Run has a Kinematic Setup. It makes the model transparent and draws the Kinematic Setup:

• single points as red spheres
• multi-point components as coloured rods between their points
• wheel axles as red rotation rings with arrows
• the Ground Plane as a red plane across the model

Sidebar¶

Filter¶

At the top of the Parts and Assemblies tabs:

Tree¶

The tree (Loaded Assemblies, Loaded Assembly or Loaded Part) lists Assembly → Part → zone.

• Tick or untick a node to show or hide it and everything under it.
• Hover over a label to highlight it in the scene.
• A Part's description is shown in italics under its name.
• A red warning icon marks a Part with open edges ("This part has open edges").
• Assembly viewer, unlocked Assembly only: the red − button ("Remove part from assembly") removes a Part. It then becomes an undo button ("Undo Remove Part from assembly"). Removed Parts turn red and added Parts turn green.

• Run model viewer, with Deltas: a Removed Parts tree above the main one lists Parts that are in the compared Run but not in this one.

Template Cases¶

Run model viewer only. Shows a Template Case's features in 3D against the model.

1. Choose a Template Case ("Select a template case...").
2. Choose a Case Data Type ("Select data type..."). The cog button beside it opens the mesh-size settings for spheres and cylinders.

The data types depend on the Template Case's methodology:

Some types have extra toggles, for example View Unmatched Zones and Explode Groups for Force Groups, or View Zoneless Patches for Rotating. Lengths here are in metres, for example the Wake Grids Base Point (m). For the settings themselves, see the Template Case editor.

Screenshots¶

Screenshot downloads the current 3D view straight away as a JPEG, at the scene's on-screen size, on a white background. The sidebar and panels aren't included. The file is named after the viewer title (the Run name in the Run model and Processed geometry viewers), with spaces replaced by _.

Kinematic Setup viewer¶

View Setup in the Kinematic Setup dialog opens a viewer with no toolbar or sidebar. The mouse controls are the same. It draws each subsystem's points joined by rods, wheel axles as red rotation rings, and a grid at z = 0 with 1 m cells. View Setup is disabled while "Kinematic setup is invalid".
