Merging Sketched Datum Curves

[ThoRig]

Community,

Consider the below image.  There are two curves created with the Sketch Tool (datum curve sketching).  Is there a way to merge these two curves to make them act as one curve?  Thank in advance.

You can create a composite curve of 2 or more curves that have G0 or higher continuity connection.

Select the first curve and use CTRL+C then CTRL+V

Hold down the shift key and select the connected curve(s) they should all be highlighted as selected

Select the exact or approximate option and complete the feature. Approximate option will create a curvature continuous curve if the references are less than G2 continuous

That will work to make a "copy" of one curve.  However, when I try to pattern a point on the copied curve (from the chain lanyard problem), I cannot make the point pattern.  It will not allow me to select the curve.  So...I was trying to figure a way to merge the curves instead of copying them.

Hi,

see uploaded file created in Creo 6.0.4.0.

I can replicate this in Creo 6, but not Creo 5. Thanks.

Thanks for the zip file.  The only thing I could not figure out is how you got DTM1, DTM2, and DTM3 under the sketch.  I made them separately, then grouped them with the revolve, and that worked.

Hi,

these datum planes were created on the fly ... see https://www.youtube.com/watch?v=unK7Rf25ywM video.

Thanks for sharing the video.

Thanks.  I will take a look at the zip file.

Martin:  I was able to replicate the same in creo 5.  When making the first datum point, I was selecting the curve from the model tree, and that will not allow a pattern.  So I selected the curve in the window, then I could set the datum point to a dimension.  Thanks.

For a pattern along curve you can only use a sketched curve. If you use the method I proposed in chain lanyard it will work for non planar curves. See the enclosed file (Creo 4).

Thanks.  I will take a look at it.
