With stone countertops, the issue is rarely one giant mistake. More often it is a chain of small deviations: a wrong vertex, a missing diagonal, a bad tie-in logic to the wall or cutout.
If the error is found only in the workshop, the cost grows fast: material waste, a repeat visit, installation delay and an unpleasant talk with the client.
Lazorex is valuable because it moves control to the site. The operator sees the contour, side lengths and diagonals immediately. If one vertex looks doubtful, it can be removed and captured again. This reduces the risk that one wrong point ruins the whole drawing.
For stone work this matters because on-site fitting is limited. The more accurate the drawing, the calmer the production step.
