Trails are a useful tool when creating the presentation (especially for assemblies with many parts) as they can show where and in which direction the part is moving. However, when creating a final exploded view it can clutter the presentation. There are two simple ways of removing them:
1.When placing the tweak use the drop down selection on the tweak menu and select ‘No Trail’.
2. If you want to edit previous .IPN’s or you have already placed the trail do a simple right click on the trail and select ‘Hide Trail Segment’, then either select ‘Current’ just for the selected item, or ‘Group’ to select all the trails in the tweak.
UCS Location of a Tweak
Tweaks can look unaligned if different UCS’s are used throughout the .ipn. As a default setting the UCS of the part is activated, this can be altered by using the drop down in the tweak menu. From here you can select ‘Local’ (the part) or ‘World’ (the assembly). If World is selected for every tweak the parts will move along the same axis in the UCS.
An alternative way of doing this would be to locate a point or face in which all the parts can be moved or rotated around. This can be found next to the drop down in the tweak menu under ‘Locate’.
Selecting Multiple Tweaks
Large assemblies can cause tweaks to not be in chronological order moving down the browser, and this can cause issues when trying to move tweaks around. A simple way of selecting multiple tweaks is to hold either ‘Shift’ or ‘Ctrl’ and then click on the individual tweaks, however, this can be time consuming. A shortcut would be to right click on a tweak and select ‘Select’ then ‘All After’ for all tweaks after the selected one in Time. The opposite will happen for ‘All Before’ and ‘Group’ will select all the tweaks in that group.
When the tweaks are selected you can align the start or end of the tweaks on the right click menu. Also, the same time frame will be kept between selected tweaks if one tweak is moved.
To change the Opacity select a component, then go the Component tab on the Presentation ribbon and select ‘Opacity’. The opacity menu will then appear and shows a slider. The slider will determine what the opacity of the component will get to, this will occur on the current time selected in the storyboard.
When accepted an expand icon will show in the storyboard for the selected part(s) which, when selected, shows a yellow box fading to a chequered background as a new row. A full yellow box is showing the part fully opaque and when it is chequered the part is not visible. The box in the middle allows the length of time to fade in or fade out to be changed by dragging the ends of the box.
The Scratch Zone
Finally, the scratch zone is a tool that can be overlooked but has some very useful features. It is placed just before the start of the timeline and edits the initial state of the model. The features you can change are: opacity of parts, part inclusion and initial orientation and view of the model. To edit the scratch zone drag the time cursor as far left as it goes so it is locked in the scratch zone.
From here you can then edit the start position of the camera by moving to the chosen position and selecting the Capture Camera icon in the Presentation ribbon. If you then want the camera to move to a different position during the exploded view move the camera and the time to what you want to be in the final position and then again hit capture camera. You can edit the length of the movement by dragging the end of the new box in the camera row.
To edit the opacity or hide parts to later bring in right click on the part and select either opacity or visibility. A pop up will appear stating whether you want to break or override the associativity.
- Breaking the associativity will stop the link between the source and the scene.
- Overriding will block the associativity just for the property that has been altered.
