with JT2Go not possible.
It is Possible with TCvis or you use from Solid Edge a PMI section.
For PMI you must save the JT-File with PMI.
You find this in the option at saving under Solid Edge.
if you ask for additional freeware for desktops based on PLMvis there are
Xpresreview 10.1.3 (32 bit based on PLMvis 10)
Solid Edge (free) Viewer 9 (32 bit based on PLMvis 10)
JT2Go 10.1.5 (32 bit based on PLMvis 10)
JT2Go 11.2.2 (based on PLMvis 11)
Inside Connect EN / View and Markup DE (32 bit based on PLMvis 10)
Teamcenter Life.. Visualisation (32/64 bit based on PLMvis 11)
NX Cam Viewer (64[32?] bit in parts based on PLMvis 11)
for use with additional funktions I think Teamcenter Life... Vis is the best version.
for working with freeware with differend funktion I think you need a combination from
Solid Edge (free) Viewer 9
this ones has the same base.
hope this helps
To request an enhancement to JT2Go, you have to be a JT Open program member and can request them through the Siemens GTAC website.
As for the 3-point cross section, that is a paid for feature of Teamcenter Visualization and cannot be added to JT2Go, as it is a free product.
