About warehouse picking route simulation

[Keenfortech]

I am an engineer in logistics planning and engineering. Your warehouse picking route simulation is really impressive, this is an abrupt request, but may I know how you develop visualization of layout and picking route in the simulation? I'd like to do the same, but don't know how, and also don't know what tool can achieve that. could you please provide help? Thank you.
And please pardon me for leaving message like this. For I've gone through all the possible links in the website you shared, but anyhow, failed to find a proper way to get connected with you.
