Removing a temporary feature without breaking references

Post by keshmaster81 »

I have created a temporary polygon feature to place datum planes on an angle so I can put holes tangent through a circle. I now want to remove the feature without breaking the datum planes. Right now the datum planes are attached to the surface of the temp feature. Is there any way to do this?

No need for any DP's in that model, waste of time and effort.

Any sketch will pocket tangent to the curve if it situated at the origin.

Put the sketch on the z-axis and pocket outward through all. You can make polar patterns of it, if you have regular spacing in angle.

Hello,

you don't need to put tangent planes for putting holes on a circular object.

View this video for reference: https://www.youtube.com/watch?v=ly3lhNZwK3o

Its a good introduction to the Lattice2 workbench.

Update: Please reference the Lattice2 workbench Polar Array tool tutorial. I think that it might come in handy with what you are doing
in your project.
