Hi Banaticus, hi folks.

Yes, normally, you can use the Dimension Tool inside the group or component to add the diameter of the hole.

If you would like this dimension entity to reside outside the group or component and be, instead, at the root of the model, you can try this:

1 - Open the group or component for editing, if not already opened;

2 - Select the dimension;

3 - Cut it (CTRL-x on PC, CMD-x on Mac);

4 - Close the group or component;

5 - Paste in place.

Notice that this will break the association of the dimension with its related geometry. Any change made to the circle will not ne reflected on the dimension.

Just ideas.

jean, that is a seriously convoluted workaround. I dont use dims in su anymore, (except for my working drawings.) For anything that needs presentation, it's straight to 'layout' for moi.

Here is Twilight Render (using Kerkythea''s rendering engine in the background) and its rendering "preference" (order) for different textures is this (as far as I remember):

materials applied on front faces (in the lack of the above) materials applied on back faces (in the lack of the two above) materials applied to groups/components

Now you really have to be careful especially with # 1 and 2 because you may have a material applied on a face in your model to a back face visible but if there is anything on the front face "behind", you will get surprisingly unwanted results.

Here is an example (really old model with lots of mistakes I made when I had only been using SU for about half a year)
http://www.septichora.hu/karmelita/karmelita.swf

It's an interactive spherical panorama. When loaded, navigate with your left mouse button and turn around to see the (very basic and primitive) rose window on the west.

The frame of it renders black and this is because inadvertently I used a back face there and could not see it until the render was complete (and it is a huge render so I have not had the time to remake it yet).

So unless you want to use external apps, you need not care too much but once you decide, you can get in trouble both with re-using your old models and even using your new ones if you have not disciplined yourself to keep face orientation correct all the time.
