use a construction line as reference

[Redro]

hello

i make a sketch and i want to extrude , but creo don't allow me to extrude because i have intersection

i want  to make a trick ... i want to make there circle  in my case as construction circle and when i exit i want to see in exterior from sketch , i create a three points but i do not see in tree to use as refference and create three holes.

can somebody give me a solution  for my problem ?

Thanks,

Hi,

use command shown on picture to remove unwanted parts of intersected geometry circles.

yes your answer is good but my idea is to use construction lines in other extrude for example as refference

is a posibility for this?

somebody have other ideas?

tks

You can't use construction lines outside of the sketch, they are for construction of the sketch only.

If you add a datum point within sketcher, it creates a point you can use as a reference  (or an axis if it's a sketch within an extrude.

Hi,

you can create Sketch feature (i.e. planar datum curve) and use it as reference in several following features.
