The solution is to create new additional layer – I named by me “Hidden”. This layer will ultimately hidden, But it's better to do it at the end, and not now.

Then we draw with a sketch auxiliary lines or sketch points, which we use to dimension the troublesome places.

Sketch elements should be switched to a layer “Hidden”.

Now we can hide the layer or show if necessary. But basically even auxiliary points I prefer to hide, Because they will be visible on prints or documentation in electronic form.

This should also be remembered, it is better not to draw immediately on a hidden layer, but on visible, And we change to hidden at the end!
