Hi Hektor, thanks, I use Greenshot and Ms Powerpoint.

Exactly what I was looking for. Thanks!

BTW, the flow of the screenshots made it very clear. What do you use to add the arrows and numbers so as to make the very clear. It would be time consuming using MS Paint : ) lol Any given tips or app name used would be appreciated.

Great script. Saved me loads of time in creating a standard switch on all my hosts to match the distributed switch.
One error I ran into though was if I already had an existing standard switch (vswitch0) and this switch already had a Port Group with a matching name and vlan ID, it would trigger the following error:
New-VirtualPortGroup : 8/25/2018 11:30:49 PM New-VirtualPortGroup The specified key,
name, or identifier 'pgName' already exists.
At D:\scripts\vmware\CopyDvsToStandardSwitch.ps1:91 char:47
+ $NewPortGroup = $vSwitch100 | New-VirtualPortGroup -Name $DvPort ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : NotSpecified: (:) [New-VirtualPortGroup], VimException
+ FullyQualifiedErrorId : Core_BaseCmdlet_UnknownError,VMware.VimAutomation.ViCore.Cmdlets.Com

Then right after the error it would still report as if it had successfully created the port group on the new SvSwitch100:
Created New PortGroup Production With vLanID 20

But in fact it had not.

If I deleted both of the vSwitches and ran it again it would go through and create all the vlans successfully.

Easy enough workaround. Thanks for putting this out there.
