Creo 7 Help

[Roman Bayramdurdiyev]

Iam currently working on automating the installs and uninstalls for PTC Creo and Creo Help. So far the Creo programs were fairly simple to create xml files and also to silently uninstall using the provided bat scripts in the program InstallManager folder. This solved the issue of manually uninstalling each component and user interaction.

My problem with the the Creo HelpCenter piece. As with Creo, it was easy to create the xml files to silently install. I have hit a roadblock with the uninstall though. If I try to run the uninstall piece by piece (such as Simulate help) user interaction is required. I have checked and can't find parameters to have it run silently without user interaction. There is also no provided scripts to streamline the uninstall.

Does anyone know a workaround? One option could be a brute force deleting of the folder and registry entries but i would prefer not to do that unless necessary as i expect residual pieces outside of the Uninstall portion of the registry.

I have managed to save a frame with a development disclaimer in Annotation for our company needs. However, I need to do that same thing in 3D viewport. Is there a way to have a disclaimer shown as default in a 3D viewport and also be able to print any designs with the disclaimer printed on it as well? Any help anyone can provde for this newby would be great.

Thanks for the quick response. We may be using a different releases of Creo 2, I say this because my annotation dialog box is named "Annotation Plane Manager" and your is "Annotation Plane" and the look is a little different. In any case, when I change the settings per your video it allows me to place the note on an object, but there is still no choice for a leader. Is there a parameter I need to turn on? Or any other reasons I don't get the "Note Types" menu to assign with leader. I do get the "Notes Types" menu when using any other annotation planes other than Flat to Screen.

These steps helped amazingly and are exactly what I have been looking for this past week. I have been trying to create 3D notes for a while now i managed to get them placed correctly with leaders but not oriented to stay parallel to the screen or viewer so not to end upside down or backwards and always remain readable. And when i did manage to get the notes parallel to the screen or 'flat to screen' it would loose the leader. The leader is important in what i am doing. In my job I am required to update our prts library with many things including '3D flat to screen annotations'. Following your exact steps i did the following to complete the notes.

Great work around. Thanks for the step by step. I still wonder why PTC is removing functonality and making it harder for us to do our jobs. This was a simple procedure before Creo. Why would you complicate things?

Side note: I've been using Pro-e for 15 years and they have always seemed out of touch with the little guy. Thats why Solidworks has kicked there #%&@ (with an inferior product) and made it harder for Pro-e users like us to find jobs. Look at the help wanted adds, it's very evident Solidworks users have an atvantage of Pro-e users.

I need help. I have several files I need to export as either .stl or .3mf for printing. Just for reference, I am trying to use Creatbot Creatware software for slicing for a D600 Pro. I cannot get the slicing function to work in Creo either, this is another problem.

I've run the geometry check, there are a couple of caution messages..."Non manifold geometry may have been created

Analyze hilited edges and redefine the feature". I have no idea what this means, nor how to fix it.

Another issue I'm having is with the slicer. I have some models which I did export as .stl, but did have a problem in slicer, other files I cannot export as .stl and have the same messages in slicer as those that I did export.

It doesn't matter if I have the file open and send to print, or create a file from start for printing, there are 2 issues (this is as far as I can get). The first issue is I cannot arrange on tray...this message pops up: STL CREATION FAILED: CLICK FINALIZE AND ASSIGN NEW VALUES TO THE STL PARAMETERS. I also get this message..."CANNOT PERFORM 3D PRINT...This model cannot be printed using the default 3Dprinting STL parameters. Define different values in the STL parameter dialog and initiate the 3D printing again". At some point, I also received a message, something about DSK and dll files not being loaded...or something like this. I don't remember what I was doing, nor did I snapshot the message. As far as I can tell, I have all files associated with additive mfg in my license file.

When you get the unable to triangulate error, is Creo showing in the graphics window the area(s) which are the source of the error? It would typically highlight the problem areas in a different color.

If Creo is not able to triangulate the model, then you will not get an STL output. This is typically due to bad geometry in the model. You must resolve this in Creo if you intend to export the model geometry using STL format. Without more details it is difficult to make suggestions.

This error is typically a result of the surfaces of the geometry not being closed (gaps or holes in the envelope) which will prevent triangulation from working. The hilited edges should be visible in the graphics window.

I'm not sure. The model will regen without warnings. If I run the geometry check, it points to some edges for extruded profile, and a sketch I used a spline to trace a profile to extrude a depth. I tried to snapshot what it is showing. What else can I provide to aid?

I do not have Creo 10 installed yet. Suppress the extruded text (P40 Warhawk....) I see in the model and then save the model in a neutral format. Try saving the model as STEP using the AP214_is protocol and export the solid if it is a solid model in Creo. Also try exporting it as a Creo neutral file. When you zip these the file size should be within the upload limits here. I can open either of those formats in Creo 9.

As a mechanical designer, I look at 3D CAD models across different formats (.stp/.igs/.stl). Especially while working with files across formats it is possible to run into challenges while running it with your home software, which in my case is Creo 4.0 from PTC. I have now used this tool for 4 years and would like to share few tricks that can be of use while working on Creo.

I will cover 5 topics and they are random commands that I had to use and which I thought I would like to share with other PTC users. Some maybe familiar, but am sure at-least one will help the end user.

The shrinkwrap command is used to make bigger assembly file into a single surface file. its sometimes difficult to send large CAD files across e mails and certain companies do not like showing the intricate details of their CAD models. This is where shrinkwrap comes in handy. However, more often it is easier to run into regeneration errors (see the image below)

2. While selecting individual surface make sure to choose "seed and boundary" and check the "include boundary surface box". Collect these surfaces individually. It might take a while selecting surfaces according to the construction (but it works).

Additional tip: Remove all the hardware, this makes the assembly very much lighter and easy to process. I can explain in another blog how to remove hardware easily without manually having to "exclude" them in simplified representations.

Neutral files is a great option to have in creo. This file is used generally while sending part or assembly files with annotations. Another user could just open it in his computer and see the existing annotations in the 3D model. Recently I came across a situation where I had many foreign file (like .igs) and had to convert them into .prt files and also have the existing parameters. These parameters were essential to drive the parameters in the drawing file. If this issue comes while working with the CAD models be ready to say thanks and welcome the neutral file in Creo.

Creo follows the parent child relationship in sketch, part and assembly. As designers it s very common to have multiple iterations from the hand sketch phase to the final drawing for prototype. So following a design methodology and rules is very important. The initial sketch for a simple extrude can cause major problems when assemblies are getting bigger and heavier.

If this is not strictly remembered or followed, half the time might be spent in fixing regenerative errors and this can become a repetitive work hereby causing a lack of efficiency. Below I will give you a technique for replacing sketching references. This is now added in creo 4.0 and comes in handy

For example if you have to change a circular sketch or curve to a square entity or line, there could be an error if there is a round feature attached to it. Or in the assembly structure that could be a reference to that edge. This is a common design change scenario. Here is where this comes helpful (see below

In the sketcher mode there is an option called replace a sketch entity ( this could have been somewhere else in creo 3 or lower versions). So first draw the intended square or line and then replace the references. In this way the regenerative errors can be avoided and saves time.

PTC for some reason removed the existing inbuilt rendering tool and replaced it with scene editor. This exist under the view tab, scenes options. The rendering is not as photo realistic as it used to be and there are few options. But the good thing with this is it comes with the basic version.

The appearance editor gives a few options to edit scene, environment, lights and background. I would say these options are enough if high quality images are not required. To get high quality images PTC has integrated Keyshot plugin. Keyshot is originally from Luxion and it is easy to use software.
