Creo Solve

[Margaretha Palone]

Ihave a problem about Swept Blend failure. I have made two 2D sections and a reference line, but I can not build a 3D part. As I pull the starting section over a specific point, it can build a part. I have tried several ways like changing the size and shape of the 2D section but I still do not know how to solve this problem. I uploaded some screenshots. If you need the prt file please let me know.

It appears that your trajectory radius is to small for the height of the section. The smallest radius in your trajectory can be not be smaller than the distance from the trajectory to the to the farthest point on the section to the inside of the radius.

Thank you very much . The explanation is exhaustive. After noticing the solution you gave, I changed the shape of the reference line (make the trajectory radius longer), and the part was successfully built! I can move on to the next step. Actually, I am making a self watering concrete plant pot. I will print it out and make a silicon mold with it, and then grout the concrete into the mold to make the pot.

I am using Creo Parametric Release 8.0 and Datecode8.0.0.0

Creo user is experiencing long delays opening up Creo files. Sometimes longer than 3-4 minutes. Mainly solid models. Sheetmetal models appear to be better.

Just to be clear, a user may have created a config.pro file and creo_parametric_customization.ui file to set up personal mapkeys, settings, etc that are isolated to this computer. If those settings are not checked, you may missing the easy answer. Config.pro setting would be my first guess.

A user just came to me with an error/problem I've never experience in Creo before. He had just changed the angle of a datum that was used to create a sketch for a cut through the part. After the change, the sketch references failed, but would not allow him to delete or replace the references. The reference viewer buttons were all grayed out, and no matter what he did, he received a "failed references" popup. We could not exit out of the sketch, select new references, or delete the old references. He was essentially "stuck". We had to exit Creo completely. Has anyone else experienced this?

Figured it out. Previous to redefining the failed sketch, there was a pop up asking if the user would like to keep the feature dependent or make it independent. If you select dependent, references cannot be changed, essentially locking you in a state from which you cannot recover. We recreated the error in the part, but changed it to independent. This allowed us to pick new references and resolve the error.

Ever since migrating from WF5, i have not been able to print directly from Creo drawings. I always have to export to .pdf first. I have tried to get help from PTC but they could not solve the issue or why it was happening. There only solution was to use the default system color scheme. We have been using ProE since 1996 and have all our config files the way we want them. I was trying to make a new syscol.scl color file but that did not seem to work either with Creo 1.0 or Creo 2.0. Any help / suggestions greatly apprcaited. Thanks!

Martin is on the right track. Creo will print using the colors shown on the screen unless you override them with the pen table. To allow users to configure the system colors however they want, you MUST use a pen table to determine how each object type will get printed. One thing to keep in mind, all custom colors will always print on pen 1 so you probably don't want to assign a color or thickness to this pen. You can move items (curves, datums, geometry, etc.) around to the layer of your choosing. Let me know if you need more help with this.

Thanks, i could use some help with these. I tried to follow the directions on the link below to set up the pen table but it did not help with printing. I know the link below is in reference to pdf print and i dont have a problem with pdfs, just printing directily from creo.

I am atttempting to write a batch file to open and automatically run a specific license, THEN if i can get past that point i would like to have it login to winchill automatically also. HOWEVER I am on the fist step and i cannot seem to bypass the license options window and i have to select enter each time. would you be willing to let me know what your backend batch file code was that when the users select #6 is starts in design essesntials instead of the native filing ..etc?

Is there is only one psf file then Creo will use that without a prompt. Our batch file deletes all of the psf files and then copies only the one down that the user wants via a batch file. Not having this psf file in the folder will cause some issues like if the user needs to run a sensitivity analysis in Simulate (because it launches another instance of Creo in the background) but it solves the issue of users launching Creo without the startup script.

Calling the .exe will always prompt for the license as it has not been selected. I create individual parametric.psf files and parametric.bat files for each license and then call the batch file directly from my script that allows the user to select the license of choice.

I've noticed that I have 1 circular reference, but when I look in the reference viewer I see 7 circular paths found. I'm having some difficulty understanding how the slide lock subassembly placement is connected to the hardware that holds the clamp plate onto the rails.

I suspect it has something to do with how I'm defining the base extrusions of each part as they are created in the assembly context. In using the default position in order to simplify the data sharing between components, I have been selecting a surface from an existing part to define the location of a later part that is being started. For example, the top and bottom rails touch the back of the B-plate, so the base extrusion of both the top and bottom rails uses an external reference to the back surface of the B-plate as the starting point for the extrusion.

Can anyone explain to me in easy to understand terms how I've formed the circular reference? And why does creo say that there's only 1 circular reference when the reference viewer identifies 7 different paths?

Also, what's the difference between a broken circular path vs an unbroken circular path? Each of the circular paths I've generated has a new symbol in the path definition, the double black arrows with a red bar struck through. Is this why creo didn't immediately flag that I had a circular reference? The alert only came up after I specifically opened the reference viewer and clicked on the "find circular references" button.

Without me understanding what your design intent is and how you want to manage it, I will keep things is general terms. If you want to discuss specific use cases with sample models then I am willing to address them as time permits.

Regarding assembly features your assessment is correct with regard to the nature of assembly features (e.g. holes through multiple parts in an assembly). I suspect that some of your issues may be related to the fact that your data sharing paradigm has created assembly references within part models. The likely issue is the difference between a copy geometry and an external copy geometry. A copy geom can be created whereby the assembly is the conduit to pass the data between parts (avoid this when possible). The external copy geometry was developed to avoid the involvement of the assembly, directly piping data from part to part directly. You should be able to externalize CG features that were created in assembly mode from part to part.

I have never successfully used shrinkwrap in a design that was released for production. I have never been able to get the geometric fidelity needed to be useful. Maybe it works on simple prismatic parts but not most of what I am creating. I am not a fan of it being used as a top down design tool in the context of my work. YMMV.

As mentioned above if you want to break down specific examples of design intent that you are dealing with and how to get that directly from one part to another without an assembly ref then post the data. Break them down to the level of part A defines X and I want to reference X in part B as a child of part A. With a simplified problem statement you will probably get directly relevant feedback.

A circular reference is caused by violating a parent child hierarchy with external references between parts. I will try to lay it out verbally. I am going to use the example of two parts modeled in part mode and ignore the assembly aspect for clarity.

When you introduce assembly features created in part models the level of complexity in managing external refs becomes onerous quickly. This is why the top down design tools were developed particularly the concept of external shared refs so the assembly is not involved in the regen of parts.

The GRV can be confusing. For this purpose I would use the .crc file text as a guide to eliminate each circular ref one at a time and use the GRV to investigate within the modeling environment that progress.
