Re: Beginners Error#1 in Crash Reconstruction 101

We also recently recalled in a response to a question sent to our forum: Expert relies soley on pc-crash for opinion? a simple thought experiment/example from an older forum post which is important for ALL crash reconstructionists to consider and understand: Classic Example of Sensitivity of Momentu...

Re: The Major Shortcoming of Simplified Momentum Simulation and Analysis

In response to a claim that my critique of simplified momentum exchange programs like pc-crash, virtual crash and others is recent, i once again refer you to our 1997 SAE paper: CRASH-97 - Refinement of the Trajectory Solution Procedure, Paper 970949 do the math, that was 25 years ago! and our messa...

Re: IMPORTANT NOTE: exe updates if your have not yet updated to version 4.0

Nov 11, 2022: Note we also found a issue where the popup menus on the 2D graphics program MGraphics were not loading.
when you start up 3D graphics and/or Medit3D you should be notified so click on the button to update!

Re: HOWTO use the Polygon Shape for Collision Interaction v4.0

some additional clarification Units are in feet, and they are the bumper height range. Cover the bumper height within this range, and in some cases try increasing it. If bumper height is 20" (1.666'). You can enter min 1.25 max 1.75, inc 0.25. (This inc is vertical) Entering 0.25 here will chec...

Quick Way to Check for changes in a file

Most simulation and reconstruction programs have a print option The following is a quick way to find any changes/differences between files: Get the program textpad Excellent program Then open ANY two files to compare: can be text, or any type of file (binary too!) For this example i made a couple ch...

Re: HOWTO use the Polygon Shape for Collision Interaction v4.0

A while back we added an enhancement as follows When we follow the fixed bumper height sometimes it may not work well all-around the vehicle. So we have to use variable bumper height with a range to pick outer-most point on the model with in that range. You can set minimum and maximum height to scan...
