Showing intersection lines

@hellnbak said:
Is there any way to have a line show where to components intersect each other (as indicated in first photo)? Sometimes it would add a little visual interest to a project.
Like this?
I haven't found a non-destructive way of achieving this effect.

If both the objects are groups/components - select them both and choose Intersect > With Selection. The edges are then created in the current context and not inside the groups.

Not the result I would have expected from that command! Thanks!

No. You can't adjust the transparency of a line as you are asking.
As to the "sparkly" edge you are seeing, I expect that's an OpenGL thing where the face behind is showing through. To get rid of it, get rid of the face behind there.
I don't get it. How can something behind something show thru? I ask for transparency for lines and it's not possible, but I get transparency on faces that I don't want?
Is there anything in this program that behaves normally, all the time?? Whether it's trying to get around the infernal inferences (which I will never understand why they don't include a command to just turn them off temporarily, at the users risk,when it's necessary for what you're trying to do at the moment) or just trying do something as simple as push/pulling a shape thru another shape, very basic shapes, and if it's in a bad mood or the moon is in the wrong phase either it just keeps pushing out the other side or won't go beyond a certain arbitrary point, etc, etc, it's beginning to feel like I spend half my time working around the strange things it does instead of just working on something in a straightforward manner. I know, I'm inexperienced at all this, and it's not like I paid money for it, and obviously there are ways to accomplish what you're trying to accomplish or there wouldn't be such a huge following or so many amazing models being created. But it does get a bit frustrating sometimes. There, I've vented. Sorry if I put anybody off. Just a noobie rant. Now I'll get back to working on the beast 
They really need more angry smilies on here

SU when it creates a face, is an infinitely thin face. So if you place a face on a face you'll get the dreaded z-fighting! SU doesn't know which face you want to show so it tries to show both. That the sparkly effect. It's not a transparency effect.
Make a rectangle and group it. Then make another rectangle over it you'll see the z-fighting. Now why would you ever want to have a face on a face? You don't because it's more than likely it's gonna remain hidden. It's a workflow thing that will eventually make sense.
As for transparent lines, why would you need this? You can turn off edges from the styles menu. You can colour edges with plugins. You can transform edges with styles. SU is robust in it's modelling approach it's just learning the correct way to approach the tasks that will take time. You're asking all the right questions to learn faster. Keep it up!

I don't want transparent lines, that would be pretty useless, I was asking if there was any way to adjust the transparency of lines, so that they still show but maybe not quite as much. It's a detail thing. But thanks for your help.

in window style choose color by material
then select a edge or edges or lines arc etc..
right click open entity info
click on the color in entity info this open colors window
then choose your color or material.this allow you to have with different colors of edges lines and faces
-
Reduce the Edge width in the current Style - Edit setting to 1, and remove all other line-styling like profiles and depth-cues.
You'll also see there that you can choose to have edges not showing, no matter if they are not 'hidden' or 'smoothed' etc.
Another way to reduce the dominance of edges at a distance is to apply a very slight Fog to the Style... -
I've been going nuts trying to figure out this "open gl" thing. Could somebody take a look at my rally wheel and, if you can figure out how to get rid of the ugly stuff around the outer edges of the rim when you view it at a distance, could you please explain how you did it? I really need to learn this.
Also, was having big problems with my model after I replaced the old wheels with my new ones, whenever I would move it, rotate it, even consider the possibility of someday thinking about maybe doing anything to it all the textures and a few other things would disappear until I stopped what I was doing. Finally figured it out - even tho the lugnuts accounted for about 6kb in file size, they added a whopping 82,125 edges to the model!! Got rid of them and the problem went away. One more lesson learned, I suspect a very valuable one - I was only concentrating on getting my file size down, paid no attention whatsoever to my edge count. Didn't realize how important it was till now. God, I really can identify with the poor Scarecrow's plight - I need a brain!

What ugly stuff? Got a screenshot?

I posted a screenshot at the beginning of this thread, but it's difficult to get a good photo of it.

The edge?
You want to hide the edge? -
Looks like your Rim is the issue...

You want to hide the edge?All I want to do is prevent the ugliness around the outer edge of the rim when it's viewed from any distance, at an angle. As I explained in my original post, it looks like it's got some sort of herringbone pattern, like you see on tv when somebody is wearing a suit with the wrong pattern on it, it seems to "shimmer". Geez, it's so difficult to explain, like trying to describe a smell, or a color. If you look at the model you can surely see what I'm referring to.

I've tried that, I've deleted the entire surface you're referring to, still there.

The edge you point at in this image?
The appearance of that will depend on your graphic card and how well it anti-alias. If you will be seeing the rim from a distance the edge will be more distinct as the edge is always 1px thick regardless of your zoom level.
If you have an object with lots of details that will be presented in a small size on screen you're best of hiding more edges.
-
Also - when you Export 2d it will look differently from what you see in screen - at least in terms of anti-aliasing.

the drawing is pretty sloppy. you have lines next to lines that should in fact be one line etc which is compounding the effects you're seeing.
that aside, you're asking to see a curved line made out of squares (pixels of your monitor).. something's got to give somewhere.. it's not going to happen. sorry.
some antialiasing settings can sort of reduce the effect but it's still going to be present no matter what you do or what software you're using. -
Ok,
if you dissect the outer rim you'll see it's made of components. Good practice...
if you analyze those components you'll see they don't meet, but overlap. Bad practice...
remember earlier i said face on face = z-fighting
These little errors occur everywhere and when you add them up you get visual trickery. Kinda Jeff's cool avatar
you'll notice a new member to the bling club soon....

It will not be viewed at one particular distance, it's just that when it's viewed at a greater distance the problem occurs. As far as hiding the edges, for me that's not an option. The edges in this particular model play a big role in it's appearance, as I indicated when I posted my original question, wanting to know how to view more edges. When you hide all the edges, on this or any other SU model, it just looks so bland, so 2 dimensional. At least to me it does.
