Multiple surface trim

Multiple surface trim

Hello, 

Does Creo have any tool similar to SOLIDWORKS' Surface Mutual Trim. As I have a surface with multiple curves and contours, and I need to delete some of them and keep others.

 

I'm using Creo 8.

Creo likely has what you need. Can you describe the functionality you need without referencing SolidWorks terminology? A simple description of what you need by annotating your screen shot would work.

Hi, as the image shows I need to create a grid in the shown surface using the projected curve in blue. So, I need to choose surfaces to keep and others to remove.

That clarifies the problem statement. I have some ideas, but it would depend on how you have built your model to determine which method would be "best".

 

In Creo you can have only "one" trimming object when using the surface trim.  Did you pattern the curves shown in your image? If so, you may be able to create a single trim and use reference patterns to automate the trim operations. I f I knew I had to create this type of pattern then I would try to exploit the pattern features to realize the required geometry.

 

You also may be able to use datum reference features to group the curves used to trim the quilt as part of the solution. This will allow you to group curves such that they can be selected as intent objects for use in the trim feature.

Defining Intent Surfaces and Chains (ptc.com)

 

My guidance for how to do this would be to pattern a datum point on the surface at the centroid of each perimeter "loop" that you need mapped onto the surface of the model. Once you have these points on the surface you can use them to drive reference patterns and minimize the manual creation of features by exploiting the pattern features. This would involve creation of the patches you want to keep in your image above, rather than trimming one large quilt many times to get the result desired,

If your model is not built in such a way to support the use of reference patterns, then you would need a different approach to leverage your work already completed.

Hi,

 

I understand the workaround you explained, but these curves are made by intersection between another surfaces so I don't have a flexibility to get them built in a way that I can use them to be like what you have explained.

 

Thanks.

Post the model here if possible. Then it can be evaluated for the options available to generate your desired geometry.

I believe you want to use trim to remove the designated areas of the surface.  Creo does not have a way to select individual areas of the surface like solidworks does.  Each area will have to be trimmed individually.  You will want to divide the lines in your sketch at each intersection so that you can pick individual curves to form a loop for each trim.


There is always more to learn in Creo.

I think in Creo 10 this is quite easy to do using the "Divide and Unify Surface"  tools.   See Surface and Unify Surfaces Enhancements

I'm not sure if the "basic" version of those tools exist in Creo 8, though...

I suspect what you are looking for is the merge feature. In the model tab it is found as shown below in yellow.

Hello @ELDAFRAWY 

 

Please refer to the following article for the corresponding commands in SOLIDWORKS and CREO.

That is not something I would ever use myself but interesting that it is there. I would say that in light of other unresolved core Creo UI issues with open SPRs I tend to question assigning resources to this rather than fixing the things the Creo users find as pain points or broken in the UI. I am sure the justification was to convert users to Creo from SW which I am not opposed to. It probably is not an either-or situation but still makes me wonder about priorities,

WOW, It's a great workaround.

 

Thanks
