Question

Why do sketches show up in no hidden view

Surely someone has asked this question, I just cannot find it.

 

Environment: Creo 3.0, part or assembly, No Hidden display style

 

I have a part that I have written text on using a sketch and that sketch can be seen no matter the orientation of the part in any of the hidden line modes. See Capture.png, text should not be visible from that angle.

 

I know I can just hide the sketch but this becomes problematic in an assembly with many items with many sketches. Besides I really dont want to hide the sketch because it represents marking on the item that's really there.

 

I have found that if I turn Fast HRL off then the sketches hide properly but then all the cosmetic threads show up. See Capture2.png, thread should not be visible from that angle.

 

I might be able to get around this if I were to make a drawing of the assembly, but this to becomes problematic when I need many images in different orientations.

 

All I want is a real No Hidden line view for illustrations.

 

Does anyone have a workaround or can you direct me to where this question has already been answered?

Brian,

just info for you ... I was not able to reproduce the problem in Creo Parametric 3.0 M030 (simple brick model with one sketch and one cosmetic thread.

Well that's odd. I just confirmed it does it for me on both 2.0 and 3.0. And other users here have had the same problem. There workaround is to set up layers and turn everything on and off accordingly.

But that's interesting that it doesn't do it for you, you think it could be a graphics issue?

If you are taking screen shots for illustration purposes, is there any reason you can't "hide" the feature for the moment and "unhide" it when you are ready? This is quickly accessed on screen and in the model tree and does not require additional layer configuration.

Krystal,

Yes, that is actually what I have been doing. The problem is finding and hiding all the features isn't all that quick or easy for us, for a simple example like the above no problem, however when I have a large assembly (which I normally do) where every bolt hole is a separate cosmetic thread it gets to be a pain. Not to mention the weird stuff imported models can do. Then after I get my image I have to be sure not to save it and close the assembly or go through and unhide everything.

Brian,

I figured that was the case. Wish I could offer a better option. I know how frustrating it is to work around these types of issues. Hope you come across a resolution or better option/workaround.

Since everyone else seems to get the same results, it's not a problem with my/our systems. This is just the functionality of the software.

I guess I am just the only one who has assemblies with lots of sketches and cosmetic threads and doesn't want to make drawings or fight layers.

I guess I am wrong to expect the button to do what it says it does!

(Sorry I couldn't resist a little jab at PTC)

I disagree. For me, at least as far as cosmetic sketches, these do get hidden when "No Hidden" display style is used:

cube_wireframe.png

cube_no_hidden_lines.png

my display settings are listed in an earlier message in this thread...

speaking of threads, the cosmetics threads still show up; but they are easily collected on a layer with the following rule:

Paul,

Agreed, cosmetic sketches do get hidden when in hidden line mode if fast hidden lines removal is off. The issue was that if you turned on fast hidden lines removal you saw the sketches and if you turn it off you saw the cosmetic threads, either way there was something there that shouldn't have been.

With that said this rules thing is something I have never seen before. (probably because I don't like working with layers)

This looks promising though, this could/would make working with layers much easier for me.

Thank you for introducing me to it!
