How to "undisplay" wrap objects- java error?

[Wayne Johnson]

I have somehow triggered the display of wrapped objects in my model. I am sometimes able to (re)hide them by resetting the display_preferences back to 0 (from 4) but other times this does not seem to work. I also get a java related exception error. The text of the error is below. I have also attached a screen shot of the rogue wrapped objects that will not hide. I am running Win10.

There are two display_preference XML elements to edit: make sure to consider the preference in both the WrapObject and in the VisibleObject within the wrap object.

Code: Select all

                            <WrapCylinder name="Gmax1_at_pelvis_r">
                                <!--Display Pref. 0:Hide 1:Wire 3:Flat 4:Shaded-->
                                <display_preference>0</display_preference>
...
                                <VisibleObject>
...
                                    <display_preference>4</display_preference>
                                </VisibleObject>
...
                            </WrapCylinder>

Thanks for reply, but both disply_prefs elements were set to zero. In general it seems there is some issue displaying the model correctly and consistently. For example, when I close and reopen the model different wrap objects are displayed than where displayed the previous time the file was opened. If I try to change display_prefs in the newly opened model I get a No enum ... message (see attachment).

A newly observed issue is that even after closing the model, the model image remains in the model window. Unfortunately this issue not predictable. I am not sure if these display issues are all related somehow.

Best,
Wayne
