Hi Mike A, yes if you draw in an image in say the Front view, then when you reverse that view so it is a Back view then you'll see the image reversed. That's normal and it's how regular geometry works too.

For example this drawn in the Front view:


Will look like this when switching to the Back view:


Background images just behave this same way, if you place an image in the Front view when you switch to the back view you'll see it flipped just the same as the geometry shown above. If they didn't then it would be weird because if you traced some lines and curves over an image in the Front view when you switched to the Back view your geometry would not be aligned with the image anymore.


If you don't want it to be flipped in the reverse view you can either switch to the reverse view when you initially place it so that it will be oriented to that view, or you can mirror an image while in the Image command by grabbing a corner grip and dragging it to the opposite side like this:

The issue I have is maybe a niche case. In the project I'm doing I have detailed tech drawings of all sides of the vehicle apart from the bottom. The vehicle is not symmetrical - there are some features on one side, but not on the other.

The drawings have been correctly scaled and positioned and all common geometry I'm creating aligns correctly in either left or right views when I'm viewing the appropriate template. The problem is that unless I'm very careful to switch image plane visibility manually when reversing views the auto-flip of the image can make the * left side look like the right side * or vice versa because the image has been auto-flipped to face in the reverse direction.

I didn't know about reversing the image in view using the corner gripper - that's handy.

Here is an updated version of the 'MOI car' example with just left and right images set up.
This clearly demos the problem. Despite there being both left and right views set up, the reverse view just uses the 'flipped version' of the other view. That looks correct in orientation - but shows the wrong side of the vehicle.

This is the problem that the script that I posted previously was supposed to address.

But it looks like it wasn't quite set up how you need it, it was assuming that the image meant to be turned on in the Right view would have "right" in its name but you have it the other way around.

Please try this updated version instead:

script: /* Reverse view under mouse and switch images */ var vp = moi.ui.getActiveViewport(); if ( vp && vp.name != '3D' ) { var toshow='', tohide=''; switch( vp.name ) { case 'Top': toshow = 'top'; tohide='bottom'; break; case 'Bottom': toshow = 'bottom'; tohide='top'; break; case 'Left': toshow = 'left'; tohide='right'; break; case 'Right': toshow = 'right'; tohide='left'; break; case 'Front': toshow = 'front'; tohide='back'; break; case 'Back' : toshow = 'back'; tohide='front'; break; } var images = moi.view.getBackgroundImages(); for ( var i = 0; i < images.length; ++i ) { var img = images.item(i); var imgname = moi.filesystem.getFileNameFromPath(img.fileName).toLowerCase(); if ( imgname.indexOf( toshow ) != -1 ) { img.hidden = false; } if ( imgname.indexOf( tohide ) != -1 ) { img.hidden = true; } } moi.ui.mainWindow.viewpanel.reverseView( vp.name ); }

Set that up on a shortcut key and when you want to reverse a view use that shortcut key to do it. That should reverse the view and also handle hiding/showing the correct images this time so that you don't have to do any manual image visibility management.

Please let me know if that still isn't what you needed.

So with that updated shortcut key, if you load your _03 file posted above it starts out like this:


Then if you push the keyboard shortcut with the updated script on it you should get this:

SOLVED! That does exactly what I need : )
Thanks for the updated script and amazing service.

As an aside... I've been using MOI for about 50 hours so far on the project I'm working on - and I'm really impressed with what you've created. One of the things I love about it - rock solid stability.

Thanks Mike I'm glad you are liking it! :)
