Creating grid of construction lines

When creating any 2D drawing, you can use a grid of auxiliary construction lines. Here, each new vertical construction line is defined by a distance from the previously created construction line. Horizontal construction lines are defined by a distance from the fixed point in the following step. Location of the origin (first point or fixed point) is defined at the cursor nearest grid point in both cases.

To define a location at the grid point nearest to the cursor, simply press the spacebar. The auxiliary mesh of points is useful for initial location of objects. Coordinates of such a location are rounded according to the grid settings.

Drawing lines using a grid of the construction lines

To define a location at the intersection of construction lines nearest to the cursor, you can press the key “c”. In this example, a line is created and each segment’s endpoint is located at the intersection of the construction lines. Generally, you can select a method of 2D location from “Snaps” toolbar. Automatic detection is available in many cases.
