pattern for holes

[terjel]

View attachment 622Hi


Im working with a car rim... I want to have the hole shown in the picture above copied around the centre of thecircular extrusion. Any ideas how to do this ?





thanks terje

you should be able to just select the cut from the model tree, right click and select pattern.


then in th ebottom left of the dashboard, change Dimension to axis, then select the axis in teh center of your model, specify the number of patterns, and the angle between them!

I am using wildfire 1.0 so there is no, axis option, is there any other way to do it??

ok, you could try Edit/Feature Operations/Copy


Select Move & Select & Dependant, / Done


then select the cut /Done


then under move features, select rotate.


select crv/edg/Axis and select the Axis in the middle,


then enter the angle, it them asks if you wand to vary anything else, just say ok or done. that sould do it!

thanks a lot, that helped...

if u want to pattern it rather than "copy move"

you must create a datum on the fly which is throught the axis and at a angle to one fo the side planes



then when making ur initial sketch u have to select the surface to
sketch on but reference the new datum on the fly. you can now pattern
relative to that angled datum.

This topic has been covered quite well, but here is another technique. If the disk is uniform, you can apply a surface transform pattern.

1. 
   <LI>Copy the surfaces of the cutout,</LI>
   <LI>Create a surface transform rotated around the axis (be sure to keep original),</LI>
   <LI>Pattern the transformed surface,</LI>
   <LI>Solidify the first instance of the pattern as a cut,</LI>
   <LI>Reference pattern the solidify feature</LI>

This way you don't have to rebuild the feature before you pattern it. In more complicated geometry instances it will reduce model size and regeneration time.
