Question

Extending Datum Feature Symbols Beyond Reference Surface

  • July 13, 2018

Is it possible to drag/move Datum Feature Symbol's beyond the referenced surface boundary? For example, the attached image show Datum A, and I'm not able to drag it beyond the surface perimeter.

The best work-around I can find is to attach the DFS to a dimension witness line, but that's undesirable because I then have to go back and add the surface as a reference. I'd like to be able to move a DFS beyond the referenced surface similar to the attached drawing image. I'm currently using Creo 4 M040, but have tested this in Creo 5 M000, and the behavior is the same.

    Looks like you're going to need to create a product idea.  PTC tech support is saying this is not currently possible.

     

    "The current behavior is working as per the specification for Creo Parametric.  It is not possible to move the DFS beyond the boundary of the selected/referenced surface."

    Thanks for the follow-up.

    This video from PTC shows it as a possbility (but not how to do it). I have opened a ticket to ask how they did it. I will post when I hear from them. Its possible it is not attached to a surface in the video.

    Chris3 -- If you create a draft DFS in a drawing, you can position it appropriately, as shown with Datum A in the video you posted. Unfortunately, this capability isn't available in modeling mode.

    If you watch the video at 1:02 the typed in datum -A- goes green which means that the datum tag is in the model. If the datum tag was defined in the drawing it would not have changed to green.

     

    Its possible I am missing something though. I am still figuring it out myself.

    PTC has added this capability to Creo Parametric 4.0 M060.  It is now possible to drag a datum feature symbol created in the model past the boundary of the referenced surface in the drawing.

     

    Here is the official verbiage from CS251133:

    "The placement of annotations in drawings is enhanced. You can drag the annotation beyond the surface boundary in drawings, providing more flexibility."

     

    Here is a video showing the new behavior:

    Thanks @TomU. When I do it I get a dashed line. Did you do something to make the leader line solid?

    Without digging into it I would guess it's a detail option setting in the drawing.  I've attached a copy of our settings to this post.  Maybe do a side by side comparison with yours and see what's different.  (WinMerge is great for this.)

    Hello,

    This is Michael Fridman, the new product manager for MBD & Detailing at PTC.

    I can update you that in Creo 4.0 M060 we have enhanced this behavior on the drawing side. so now you can drag the DFS in the corresponding view out of the boundary.

    On the model (or MBD) this will maintain as is for now.

    Hope this helps
