Creating A Crash Animation - MicroSurvey

IMS Course Training StandardApril 24, 2017Creating a Crash AnimationThe ExerciseAn animation showing two symbols following a path to a point of impact can be created in theIMS Animation module. The drawing you work with requires the following elements: The Drawing or Pointcloud with the elements you need to see.Measurements that can be used to create 3D polylines that define the paths of thesymbolsSymbols should be inserted into the sceneOpening the drawingA drawing containing the needed elements can now be opened. We’ll use it to create a pathand then create a fly through animation.1. Start IMS2. Pick “Open Scene”3. Navigate to the location “Intersection” is stored and openthe drawing.Drawing the PathsYour drawing has points stored that we canuse to guide drawing a path. Points 10 and11 define the first path. Points 20 and 21define the second path.Entity SnapsLeica Geosystems Incident Mapping Suite CTS – 2017 MicroSurvey Software Inc - 1 -

They ensure that an entity thatyou are drawing adopts the exact X,Y,Z coordinates of the entity you are using as a guide. Find the Settings group in yourDraw RibbonClear all active entity snaps(“Active” snaps are indicated by theorange highlight)Set the “Node Snap” activeConfiguring your LayersLet’s freeze the hatch layer, it can sometimes cause visibility issues: Select the pulldown to the right ofthe layers dialog.Find the Hatch layerPick on the freeze/thaw iconAny hatches in the drawing are nowhiddenLet’s set “Animation” as the current layer: Select the pulldown to the right ofthe layers dialog.Move your mouse so that“Animation” is highlightedLeft click so that “Animation” nowshows in the current layer display.Drawing Path 1“Draw a 3D Curve” is a command that is ideal for creating animation paths, both 2 Dimensionaland 3 Dimensional.Leica Geosystems Incident Mapping Suite CTS – 2017 MicroSurvey Software Inc - 2 -

Use the same steps as before to create this path on the“Animation” Layer. Start at 20Ensure node snaps are onRemember to type “D” to draw theline when you are finishedSave your work.This drawing already has two vehicle Symbols inserted so you can focus on learningthe steps in an animation. This can be accomplished by opening the Symbol Librarian onthe “Draw” ribbon:Symbols can also be imported from Google Sketchup Warehouse by using the ColladaImport tool.Leica Geosystems Incident Mapping Suite CTS – 2017 MicroSurvey Software Inc - 4 -

IMS Course Training StandardApril 24, 2017Creating the AnimationWe are now moving on to the next critical step, creating an animation file and assigning twosymbols to their paths. Find “Animate” on the AnimateRibbonSelect “Symbol” and “Add Symbol.”Inserting Symbol 1 Select “Pick” and then select theblue sedan symbol that ispositioned to the left of the road Select “3D Polyline, Straight” andthen “Pick.”Select the 3d polyline between 10and 11 Leica Geosystems Incident Mapping Suite CTS – 2017 MicroSurvey Software Inc - 5 -

Creating a Collision Animation IMS Course Training StandardPick “Apply” and now you canconfigure your Symbol Offsets.We want this symbol to move alongthe ground as a rolling vehiclewould. Use the “Jogger” buttons toadjust the Z offset so that the blueplane representing the ground is atthe symbol’s wheels.There is no need to adjust therotation value as the red arrow isshowing that the forward directionon the symbol is correct.Select “OK” to complete theoperation.Inserting Symbol 2Repeat the steps to insert the Green Wagon Symbol and link it to the path that connects 20 and21. Notes:The path is between 20 and 21This symbol requires that youadjust the “Z” offset slightly so thatthe blue plane is even with thebottoms of the tires.The Result:Leica Geosystems Incident Mapping Suite CTS – 2017 MicroSurvey Software Inc - 6 -

Let’s configure the track to show that and calculate a time from the known distanceand speed:Leica Geosystems Incident Mapping Suite CTS – 2017 MicroSurvey Software Inc - 7 -

We must use the longest track as the overall length of theanimation, and adjust the shorter symbol track so it ends at exactly the same time.Leica Geosystems Incident Mapping Suite CTS – 2017 MicroSurvey Software Inc - 8 -

By default they are rendered asWireframe entities as this is more efficient.
