Hello,
I am using PTC Creo Parametric 2.0 and I really need to edit an .igs file!
I can import it and open it but i cannot modify the geometry or like modify the original sketch...I am just able to move the parts.
What I need to do is to create another sketch over the geometry and the 3D I import, cause I need to draw and add another "piece" to it.
If anyone knows how to do it please reply! 
Thanks in advance

Having read all these fine comments, I sense a bit of frustration with Creo
I've been working with Pro/E since 1999. Came from a company that was using Unigraphics back then.
It was a HUGE step backwards.
Over the years I came to understand Pro/Engineer and really like the way it works. Though I'm still missing some of the functions from the old Unigraphics.
Windchill was added along the way and new problems arrived.
2½ years ago I joined a company which had moved from Inventor to WF5 due to a corporate decision.
NO happy workers there. Windchill was f...everything up, and people were generally frustrated.
It took more than a year to correct Windchill 9.1M030 behaviour and make people accustomed to WF5. They're not happy with it, but can their day to day work without too much hassle.
Now we've moved to Windchill 10 and a much better UI. Still problems, but we're working on them.
My point here is: Why do I have to spend so much time on making things right and teaching basic CAD stuff to experienced Inventor users?
I want to do engineering in WF5/Creo and not spend so much time on system administration.
PS - I think Creo 2 is a huge step forward, but see BIG problems ahead when we change from WF5 to Creo 2.0 (again corporate decision).
So Bjarke...
You want to go through the pain of working with a trail file just so Creo will open up the last assembly you were working on? Why not just use the Open Last Session button (shown below)?
Trail files are a pain in the neck... they always have been. But you can usually add in any necessary data for automatic entry. When you start Creo and you're presented with the message saying your license has been returned and asking you to press "OK". This interrupts your custom startup trail file. Go ahead and press OK... then EXIT Creo.
Go find the trailfile that Creo just created from the last session. The message window and the prompt to select OK will be recorded. Grab these lines from the trailfile and add it to your custom "startup trail file". Of course, on days when you are no returning a license, the trail file might fail because you don't have that "OK" prompt. But this is the chance you're taking using a trailfile in this situation.
I'd suggest using the Open Last Session button instead. If this doesn't work for you, consider making a mapkey like $F12 (the F12 function key on the keyboard) and having this execute your trailfile. That way you're always able to execute that startup trail file no matter if you're prompted to hit "OK" or not.
Thanks!

I hate the creo GUI with a passion, ESPECIALLY the ribbon (see my other posts), but I will tell you SW doesn't hold a candle to Pro/E when it comes to geometry creation. They just NOW got conics? We had 'em in '95 (v15)or earlier. Top-down design in Pro/E is also much better. And, honestly, having used both, I liked the Pro/E interface (pre WF, and especially pre-creo) better and for me it was easier.
For a box around a line of text, start it with: @[ If you want a box around a bunch of text, or a triangle, create a symbol. It's not that hard.
When you can create in SW the shapes I can in Pro/E (see my album), then come tell me SW is better. 
PTC has made things so confusing anymore that I don't know, or even care, what's what. I call it Pro/E, and as far as I'm concerned, what I'm using still is (creo elements/pro 5.0). I still much prefer WF4 (though I still don't like the GUI vs the older versions). I guess I don't know or have even seen what the other stuff is. PTC dropped the ball on this too, by making it so confusing......
Perhaps they should further rename it "Pro/CREATE"?
Hi,
I would really like to have a copy of your spreadsheet.
I start in another company in a couple of months, and they use SW and Siemens NX.
I've never used SW but I look forward to it.
Siemens NX may be more expensive than Pro/E but it works...!!!!! - really well
Having the spreadsheet can give me an idea of what comes ahead.

Thanks, guys. Yes, I am super confused on all the PTC Products and why they don't completely change the names. For example, when you launch Creo Elements / Direct Modeling, the name CoCreate still appears during launch. Also, when you hover over the icon on your taskbar, it's CoCreate. Also, the ACTIVE forum (http://www.cocreateusers.org/forum/) is named CoCreate. WIth all the confusion about the names, I was not surprised that Creo 2 might be another name for CoCreate or even Pro/E. It just seems like the entire company is sloppy. SolidWorks has a very active and useful discussion forum. CoCreate only has 3 pages of user groups; SolidWorks has dozens, and a very active user group community. I'm disappointed in the company and especially the software. But my employer uses it, and I love my job, so I can't complete. I think naming it PRO/Create is a GREAT idea! 
. I guess I'll migrate from here over to the CoCreate forum. Thanks again! @MandoAnne on Twitter, and I'm also on Linked In - Anne Yust.
100% WRONG Carl. Change for the sake of change, and to justify the developers existance and salaries is BS. The steering wheel, brake pedal, shifter, and throttle in a car are all where they have been for many years. Why? Because they work best right where they are. Change that makes a product better or more efficient is a good thing. This ribbon GUI is bad change, so is the loss of some of Pro/E's functionality. Having used Pro/E for over 15 years now, I can say that up until creo all the changes were good and worthwhile, and I always looked forward to them. Hated the WF interface, still do, but at least it's functional and doesn't get in the way too much. The creo GUI flat blows, and does nothing but slow us advanced users down.
Maybe you guys don't have any, and that's why the lousy GUI isn't an issue for you.....
When you can create the models I've got in my album, then you can tell me how much better the GUI is.
Well, I can tell you that dwgs take 2-4 times as long, because I have to keep going back and forth to the ribbon from the field of the drawing where I'm working. In older versions, you did not need to do that. You could do anything to any object in your field of view. Now you cannot do many things you used to be able to do, even by hitting the "Alt" key. For instance, in the layout tab, you cannot select text on the dwg. If you hit Alt and select it, you STILL cannot do a properties and change the text, which is 99.999% of the time what you WANT to do. You can only delete, and do a few other things. The mapkeys to open or start a new object used to work whether in modeling, assembly, or dwg mode. Now, they only still work in model or assy mode, and a whole NEW set of mapkeys must be created and used in dwg mode. Up until creo, with few exceptions, the same mapkeys worked EVERYWHERE. THIS kind of stuff is what I'm talking about. Us, ahhh, OLDER users have worked up to a certain speed and fluency, and the ribbon throws a huge monkey wrench into that, drastically slowing us down. If the interface worked as well or as fast, but was just different, there'd be griping, but eventually we'd get used to it. Not so here, where there is and always will be a dramatic drop in productivity until they fix this.
BTW, I absolutely hate the ribbon in MS prodiucts, though they seem to be done a lot better than in PTC's products. I absolutely loath windows 8. Ugh!
The bottle was tough, tryin to get it to shell at .010" thickness, and keep the wall thickness thicker at the top was tricky. I made it by measuring, as best I could with calipers, and existing Coke bottle, and added the handle as desired.
BTW, that text you're using is really hard to read. On another note, I see you picked the guitar avatar. I'm listening to some Joe Bonamassa as we speak.....

I won't comment on rest of your post, but this one I can address. AFAIR, you switched from WF4 to WF5 and it's true you can't do those things you listed. On the other hand, it was largely addressed in Creo Parametric 1.0 and most of this "tab-context" filter has been removed. I think now, in both versionf of Creo, the only thing that is left of this filter, are table operations. For the rest of the objects (or at least for most of them), you can select them and use context menu for them regardless of the active tab. It doesn't change of course, that tabs are still there and most advanced tools are there and not in right-click menu. But still, it's something you might consider as a step in right direction (apart from removing Ribbon altogether, which I don't suspect to happen anytime soon ).
