Inventor Studio Animate Positional Representations
Positional Representations Notes • Start new assembly file and assemble the Track. • Place 4 Sub Assemblies of the Train. • Make sure all the wheels were constrained prior to assembly. • Make sure Train sub assemblies in the main assembly are made Flexible. • Suppress the angle constraint used to drive the wheels in previous train activities.
Position1 • Expand Representations in the Browser and right click on Position and select New. • Expand Position : Position 1 and name the position, 1 to reflect the first train position . Make a total of 8 positions. • Double click on position 1 and constrain the train to the track Mate .4, Flush .7, and Flush -2.75. • Double click on Master under the Position : 1 and apply an angle constraint to the track face and wheel workplane. (Parameters) • This angle constraint is used to rotate the wheels and must be applied to the Master.
Position 2 • Double click on Position 2. • Right click on the Flush constraint used for Position 1 (back of train to end face of track) and select Override. • Set override distance (33.25) • Double click on Master.
Parameters • Select Parameters. • Scroll down and click on User Parameters and select Add. • Click Parameter Name type train1. • Click Unit type deg. • Click Equation type 0deg. • Find the angle constraint previously applied to track face and wheel workplane and name it train1 in the equation column.
Inventor Studio • Applications pull down and select Inventor Studio. • Select Animation Timeline. • Select Animation Options on timeline. • Set the time for the animation.
Positional Representations • Select Animate PR. • Set Representation Start To 1 and End to 2. • Specify Time Start 0 sec and End 5 sec.
Parameter Favorites • Select Parameter Favorites and check the box under Favorites and click OK. • Expand Animation Favorites in Browser and right click on parameter train1 and select Animate Parameters.
Parameter Favorites • Set the End to 1834 degrees. • Circumference = pD (3.14 x 2.25 = 7.065). • 36” / 7.065 = 5.095 x 360 deg = 1834 deg • Specify Time Start 0 sec and End 5 sec and click OK. • Animation Timeline select Go to Start and select Play.
Position 3 • Return to the assembly environment. • Place the Pivot part. This will allow the train to rotate around the oval track section. • Constrain the Pivot and Train2. • Insert center of pivot to top inside arc of track. • Mate the bottom face of train2 to top face of track .4 offset. • Mate side face of train2 to side face of pivot 12.05 offset. • Angle top edge of pivot to top edge of track 0 deg. • Flush the back face of pivot to back face of train2 2.5 offset. (pivot size is .5 so -.25 from 2.75 to center body in the middle of track). • Angle the back face of train2 to back face of pivot. • Angle the wheel workplane to top face of track. (Parameters) • Double click position 3 to set the train position. • Double click Master. • Click Parameters and repeat previous process name it train2.
Position 4 • Double click Position 4. • Locate the angle constraint previously applied to edge of track and edge of pivot and right click select override. Set the override to 180 deg. • Double click on Master.
Inventor Studio • Return to Inventor Studio • Select Animate PR. • Set Representation Start To 3 and End to 4. • Specify Time Start 5 sec and End 10 sec.
Parameter Favorites • Select Parameter Favorites and check the box under Favorites and click OK. • Expand Animation Favorites in Browser and right click on parameter train2 and select Animate Parameters.
Parameter Favorites • Set the End to -2128 degrees • Circumference = pD (3.14 x 2.25 = 7.065) • Oval Circumference = pD (3.14 x 13.3 =41.763) • 41.763 / 7.065 = 5.911 x 360 deg = 2128 deg • Specify Time Start 5 sec and End 10 sec and click OK • Animation Timeline select Go to Start and select Play
Position 5-6 and 7-8 • Complete the other half of the train presentation by following the process previously applied.
Animate Fade • To complete the animation Animate Fade will be applied to the four train sub assemblies to make it appear that there is only one train going around the track. • Select Animate Fade and click on train assembly 2,3, and 4 in the browser. • Animate Action select End set to 0 • Time Specify or Instantaneous Start 0 and End 0.
Animate Fade • Animate Fade the timing for train1 to disappear and train2 to appear instantaneous to one another during the animation. • Select Animate Fade and select Train1 in the browser. • Animate Action select End set to 0. • Time Instantaneous End 5.
Animate Fade • Select Animate Fade and select Train2 in the browser. • Animate Action select End set to 100. • Time Instantaneous End 5.
Animate Fade • Select Animate Fade and select Train2 in the browser. • Animate Action select End 0. • Time Instantaneous End 10.
Animate Fade • Train1 should now disappear at 5sec and Train2 should appear at 5sec and then disappear at 10sec. • Complete the animation process. • Note: Editing the Fade in the Animation Timeline is tricky, click on the box at the start or end of the fade bar and right click.
Animation and Render • Animation Timeline select Record Animation. • Lighting Style: Four Color • Scene Style: XZ Reflective GP • Select Render
