hidden line removal algorithm in DRAW

Does the hidden line removal algorithm work in DRAW?

Please look at the following commands.
With mode 1 (Shading), the box is displayed, with mode 3 (Exact HideLineremoval) it is not.

pload ALL
box b 10 20 30
vdisplay b
vsetdispmode 1
vsetdispmode 3

Dear Mauro,
You can consider it as documentation bug.
I suggest you to register it in Mantis Bug Tracker.
For AIS_Shape mode 3 is not implemented.
If you want to turn on HLR mode =>
- select object in the Viewer
- press button 'h' (works like switch)
After that you will see HLR presentation of the selected object.

Using mode 2 is not effective.

Dear PG,
As you may probably know, a special web site dedicated to Open CASCADE Technology collaborative development is available at http://dev.opencascade.org/ during a year or so already.
Every person who wants to contribute to OCCT development by providing bug reports, fixes, improvements etc. can register on this web portal and use the available resources to make contributions.
In particular, any person who wants to report a bug in Open CASCADE Technology is advised to use our public Mantis bugtracker (http://tracker.dev.opencascade.org/) pointed to by the 'Resources' page of the portal (http://dev.opencascade.org/index.php?q=home/resources).
Any registered user can report problems in OCCT software using this Mantis bugtracker and following the workflow and procedures described in the document 'OCCT Contribution Workflow' (http://dev.opencascade.org/sites/default/files/documents/OCCT_Contributi...).

Dear Sergey,

under http://tracker.dev.opencascade.org
I cannot find any "register" key or link.

I have also looked under My View | View Issues | Change Log | Roadmap | My Account

Even OCCT_ContributionWorkflow_V3.pdf does not say HOW to register.

By the way, in http://tracker.dev.opencascade.org/main_page.php there is an obsolete link:
clicking on the red rectangle "New (Maintainer) fix provided"
the V2 version is open instead of the V3 one.

Dear Mauro,
Read more carefully my previous post:
"... is advised to use our public Mantis bugtracker ... pointed to by the 'Resources' page of the portal http://dev.opencascade.org/index.php?q=home/resources).
The last link has 'Resources' page where you can register.
After registration you will have access to the listed before links.

Sorry, I was not clear:
I AM registered already.
I meant registering THE BUG.

How does one insert a bug in the Mantis bugtracker?

Dear Mauro,
Open a corresponding link referring to the Bug Tracker - http://tracker.dev.opencascade.org
At the right up corner find,please the label "Project". The selected value should be "Community".
If it is not the case choose the "Community' from the list of the corresponding combo box.
Select menu item "Report issue" from the menu panel located one line lower than label "Project".
The registration page will appear. After that follow the procedure described in the chapter "2.2. Issue registration" of the document 'OCCT Contribution Workflow'.
