Pattern Problem

Morning All,

I'm struggling with the pattern function in Creo 3. See image below.

Basically, I'm trying to pattern a hole feature along a sketch line on the face of this component. But no matter what I do or what settings I change the hole pattern runs off the sketch.

The base component is 2.8m long, its a ø6mm hole and the spacing is 150mm pitch. The first hole is bang on the sketch line but by the end of the pattern

it looks like this....

Any ideas what I'm doing wrong????

Thanks. James

During pattern creation, see if you have the option for an alternate origin under options.

If this doesn't work, try a point pattern. Place a point on the curve and set a ratio value or real value. Now pattern the point using the value for the point's location along the curve. Now create your first hole on the 1st point of the pattern. Then pattern the hole using a point pattern and again, select an alternate origin making sure the hole patterns correctly. You should be able to get a reference pattern option but if that fails, select the point pattern

Thanks Antonius,

Setting the origin to the start of the sketch line corrects the problem
