I'd like to draw a construction line (sketch) from a centering axis. Is it possible?

indeed I would like to dimension the two countersinks starting from the center of the axis (see IE)

Hello

Do you actually want to stretch the axes of the counterbores?

By selecting the axes and pulling the ends with the mouse it should get bigger

What you can do is a bubble on the countersink. Then you just have to enlarge the view to have a zoom that suits you and there, you can dimension without worries:)

Hello

Yes indeed you have to create a sketch of the axis line or construction line from the center of the countersinks to the center of the axes for the software to offer the dimensions in oblique, select sketch then enter the view draw the sketch then exit the view and dimension, the oblique dimension is proposed automatically close to the axis created with the sketch and straight when you move away of this axis.

I guess you want to rate like that.

Hello
The question can be understood in several ways (for my answers everything is done without a sketch, only with the axes of centering):

The size of the centering axes can be increased by zooming in and dragging the end of the axis. You could also have created the centering axis on the countersink and not the smallest diameter.

If you want an axis that goes through the centers of the two countersinks (not vertical) just play with the options during insertion.

If you want to position your A-section view on the countersinks, you have to edit the sketch of the cut and add a constraint with the center of the countersink and the center of the part. Like the others: it may not be your pb. Give more info.
