Radial Pattern Problem w/ Skipping Featrs

[slingblade]

ProE Wildfire 2<?:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" />


When I made a radial pattern (turbine blades in a tutorial) I was able to make the pattern and to eliminate or skip some of the features by clicking on the black dots and turning them white.


When I tried to skip or eliminate the first feature however, ProE wouldn't let me. The reason I wanted to do this was because there are two sets of blades on the turbine. I wanted to put the section sketches on the same plane and just skip the first instance of the 2nd set of blades to offset the pattern. Thiswould allow me toput one of the second blades between each of the first set of blades. I used this method in SolidWorks2003 some time ago and it worked.


I wound up creating a plane for the section of the second set of blades at an angle from the Right Plane and it worked but it is not as convenient to make the model parametric this way. The angle of the plane for the blade cross section as well as the second trajectory line both have to be managed with regard to the number of blades.


Does anyone know how to skip the first element in an axialpattern of features or rotate the pattern around the axis by a given angle?

About all you can do is insert a datum plane before your feature then redefine the patterned feature to use that as the Rt. plane when sketching. Group the plane and the feature then pattern. This is just like it was when creating datums on the fly in 2001. The only difference is that you have a group pattern based on an angled offset plane, instead of a simple pattern.
