Align Vertices

[ruslankostiuk82]

Hi Everyone,

I need to align the C vertices with the other two A and B so that they are in line, as in the example. Dimension D must be maintained.
I will be grateful for your response.

In snapping options enable axis constrains. Drag C on XZ/YZ or whatever axis plane there is that excludes the axis of D dimension.
