Snap to grid using knife tool I have a situation where, after extruding an angled face, I need to make an edge of it flush with the grid lines. I tried to illustrate what I want to do with the image below. Note, the new location does not lie along the intersections of the grid, only along the X line, so I cannot use snap to grid.



I believe the best way to accomplish this would be with the knife tool, but I need a way to snap it to the grid in order to get accurate results. Is there such an option? Bisect would also work.

I am aware I could use a second object and intersect them to get this result, but I would prefer if a tool could accomplish what I need, as my current project will involve a lot of this.

Snap a 3D cursor anywhere on that X line you need.
Create a new plane.
Press R to rotate, then X to lock to X axis and rotate a plane so it would be intersecting your figure.
Go to modifiers tab and add boolen modifier.
Select your figure as an object.
Apply a modifier.


It should create a vertice on the intersection that you can use with snap tool.
