Creo Parametric Ideas

Hi,   in optic of MBD, it was useful to have the capabilities to create some table in 3D with Repeat Region (with the same capabilities of the 2D)         ... View more

Currently you can not use a parameter in the additional text fields of a GTOL.  If you try you will just get the text as you typed it and not the parameter value.  See attached image for an example.  This should work like notes, and virtually every other place within Creo.  My main focus for this request if for model annotations but the same could apply to drawing annotations.  This does not work in Creo 3 or 4.   ...

Hello, Sometimes, after defining a Combined state with 3D annotations in Creo Parametric, when exporting the assembly to pvz and opening the viewable in Creo View, the combined view opens in a different orientation (translated in Creo View compared to whats defined in Creo Parametric 😞   The user opening the same combined view inside PVZ can think its empty or in best case need to translate the combined state to have a correct display ! Can you please Correct this behavior : an orientation defined in Creo Parametric for a combined state should be always exactly the same when reopened in Creo View !   Associated PTC Case : C14627537    Thanks in advance ...

Modelcheck should be able to handle 3D annotations, combined states, ... (elements of the model based definition for a 3D model).   To check the quality of a 3D model and 3D annotations is something really important to for a company involved in the model based definition and the digital twin. ...

There are several use-cases for hatching of surfaces in 3D. - Visually indicate the direction of surface finishing, e.g. for polishing - Differentiate between two surfaces which appear to be on the same level but actually are not - Indicate an area of interest in the 3D - Indicate an area off-limits for manipulation - ...   I imagine the feature to work something like this: - You could choose between existing hatchings - You could choose the angle and spacing - Maybe orient the hatching according to other geometric elements - Control visibility of 3D hatching with layers should be possible Example dialog ...

Hello,   it will be interesting and usefull to have the possibility in the 3D MBD , to attach a symbol on an 3D annotation (dimension or Gtol). Actually it's possible only on the drawing.       ... View more

I could bring part numbers and description (parameters) of all the parts of an assembly in the annotation note (Parametrically). But i could not bring the quantity of all the parts parametrically (It needs manual entry as of now). If PTC can provide option to make it parametric, It will completely eliminate preparing assembly and installation drawings, which will save hell lot of time and effort of all the Creo users. ...

Hello, In 2D drawings, if we select several dimensions we can move all of  them simultaneously. However, in 3D annotation (MBD), we have to move the dimensions one by one. It would be very useful to have the possibility of moving all the selected dimensions simultaneously in 3D MBD, as we can do in 2D.   Best regards, Amaia Azkue ... View more

It´s fundamental that the drawing could mauelly updated if a combined state in the model has been updated. Without this function MBD is not easy to use where drawing of a model is required.   Also it would be nessary that you can compare in the drawing what have been changed and the current state. ...

Inside an MBD world a full annotated model is the basic for a digital production. How do we handle REUSE feature from other models or out of a library? OK, Merge is a nice solution, and is supporting the digital MBD approach 100%, if there is no dimension or features which need to get changed or modified or suppressed. As soon as a merged library part get modified, it's not a standards library file anymore (inside Windchill) and need to get copied and renamed. A variable reuse of feature is missing inside CREO. More and more library parts are similar and can be used in different sizes, that’s a kind of flexible library reuse part. Inheritance Feature is the answer for it. But there are some limitations inside an inheritance feature, because it’s working complete different as a merge feature. The idea of an inheritance feature is to make a reuse feature flexible and possible to modify. First, some advantages of an inheritance feature: Dimension modification during placement suppress feature, modify parameters An Inheritance feature is like a flexible reuse of single or multiple features which are fully annotated and can be stored inside a write protected library Without loosing the reference to its base model But there are also a lot of disadvantages, which will block every company to use inheritance feature for a flexible reuse approach. What needs to get changed to support an inheritance feature to fulfil MBD inside a digital thread. Datum System can cause issues and conflicts, here it should use the same solution as MERGE feature Datum symbol cannot get moved to another position GD&T annotations are uncomfortable to move Colors out of the library model (base) should get transferred In case of pattern, datum system is wrong. Here each pattern instance needs his unique datum system. Creo should rename for each pattern instance the datum symbols and relations to corresponding GD&T tolerances. Like Merge is doing. A Datum sysmbol is unique Inheritance should support a pattern ISO GPS conform by using correct Datums PTC need to modify inheritance feature to work the same way as a merge feature. Without those requested changes, a reuse of feature in a flexible way is not possible. Merge is no solution here to support flexible inheritance features for an automated and controled reuse process. ... View more

The need of this functionality arose when we started using solid weldings in assemblies and when we started annotating assemblies in MBD. Initially, case 14976049 was opened requesting more info but unfortunately we obtained the explanation of the link below. At the moment it is not possible to do so. https://www.ptc.com/en/support/article?n=CS31266 This functionality would make our lives much more easier and would enhance Creo Parametric performance and flexibility. For example: It would reduce the number of files to be managed by Windchild (PDM), using only one single file (with several simpl. reps.) instead of managing one file per instance if the suggested workaround (family table) of the article were followed. It would be very useful to deal with assembly cuts (i.e: machinning operations at assembly level) that modify the geometry of the components adding them to simplif. reps. and checking the influence in the total weight of the assy. It would be very useful to add welding features to simplif. reps. and check the influence in the total weight of the assy. When you are working with solid weldings, there is a problem because when you create a simplified representation excluding all, you still have solid geometry (created by the assembly features of the solid welding seams). In general would be very useful to work with assemblies that include features that affects the mass properties of the assembly. It would be very useful to help populating the assembly for MBD. Combined states could be created easily based in different simplified representations where you include/exclude the features that modify the geometry of the components with the advantage that the mass properties of the assembly in each representation could be evaluated independently. ...

In 2D, if you show the axis of the pitch circle, the axis are aligned toward the center of the pitch circle and you see the actual pitch circle: In 3D (MBD), the axis of the holes of the pitch circle are always aligned vertically/horizontally. The pitch circle is not shown. The behaviour in 3D should be exactly the same as in 2D. ... View more

the goal is to - Inherit driving dims with copies of geometry and fusion. - Link intent reference features to manage the semantics of patterns with driving dimensions. - Improve PVZ, STEP AP242 and QIF exports. - Extend the GD&T Advisor use to inheritance dependence parts. - Continue exporting the geometry model with middle Dim boundaries option     actually my issue is when I practice a top down design process. I define reference dims in a skeleton. Then I share the geometry in components.    - when I create a drawing of that models using copy of geometry, the principal dimensions are missing (must be created) - if I create annotations  in the skeleton to share them with the copy of geometry, it's double work. Other thing if I create annotations is the TA. I'm able to use the annotations for Tolerance Analysis, but their dimension boundaries do not control the geometry, so the export for NC cannot be centered in the middle boundaries. And if I use the driving dims for Tolerance Analysis, the annotations are not up to date!     Hope you will quickly do something so that we can share skeleton driving dimensions  in "read-only" with copies of  geometry, as this is a problem that has been going on for too long. ...

  If you use the Holes feature to create annotations after creating a hole, the arrow does not point toward the hole center. When measuring the diameter, the arrow points to the hole center. The user tries to use the drawing annotation by modifying the holetable, but the arrow direction is not centered, making it difficult to use.                                                   (The direction of the arrow measuring the diameter is toward the hole center.) ...

Add the ability to create a GTOL with leader where the leader is perpendicular to the selected surface.  Currently this is possible when selecting an edge as a reference.  Please refer to the attached images, there are two GTOLs, one is created by using an edge and one is created by using a surface reference.  The edge reference GTOL is exactly perpendicular to the edge, in the same way, we would want a perpendicularity icon when creating the GTOL by using surface reference.   ...

it would be great to have a way in Creo when exporting to 3D PDF that we could set the different combined state tabs to be on separate sheets.  Also, if there was a way to set up the 3D PDF with a template that had our company information already setup similar to a drawing template.  This would allow us to put common notes, tolerancing, and company info in without having to add it every time we created a file. ...

It would be very helpful if model annotations could be related to one another, similar to how drawing annotations can be related. Currently, it is cumbersome to move annotations (such as a flag note symbol and a dimension) to be on identical planes in 3D space, and impossible to relate them so that they move together when dragged to a new location.    Alternatively, allow symbols to be added to annotations in the ribbon with intelligent above/right/left/below placement fields, like how text can be added to geometric tolerances with the Additional Text ribbon command.     ...
