Precision Modes

nanoCAD, as with other CAD systems, allows precise geometric creations (up to 14 decimals).

Using precision tools allows:

·         quick implementations during the project,

·         elimination of errors and inaccuracies in the dimensioning,

·         elimination of errors in the measurements of angles, length and distances, which were not dimensioned in the drawing,

·         avoiding problems occurring with hatch, due to open contour,

·         reducing time spent on the control programs for NC machines (because it is not necessary to edit inaccurate geometry of the parts) etc.

nanoCAD provides precise geometric creations in two ways:

·         precise coordinates of object points and

·         using precision modes.

Precision modes allow:

·         place points on the rectangular grid (SNAP, GRID modes);

·         use object snaps to snap to characteristic points on the vector and raster objects, for example to the endpoints of a line or to circle center (OSNAP mode);

·         the use of tracking lines to place a created object in relation to other objects (OTRACK mode);

·         snap to specified angles and define distances using polar tracking (POLAR mode);

·         create and replace objects parallel or perpendicular to coordinate axes (ORTHO mode).

Precise tools are controlled in the context menu by the buttons and in the Drafting Settings dialog box (Tools> Drafting settings).

Buttons to switch between precise modes are in the status bar.

The orange color of a button shows that the mode is switched on.

All or several modes can be switched on at once.

Three ways to switch on/off the modes:

·         Click on the button.

·         From the context menu of the button select On or Off.

·         In the Drafting Settings dialog box (Tools> Drafting settings) select or deselect the check boxes: Snap on (F9), Grid on (F7), Polar Tracking on (F10), Object Snap on (F3), Object Snap Tracking on (F11), Object Snap 3D On (F4).

To open the context menu with the commands to control modes:

1.      Place the cursor in the status bar,

2.      Press the right button,

3.      Select/deselect the required mode.

Context menus are closed after selecting an option or after clicking the mouse button outside the menu. To exit the context menu of the SNAP and O3D SNAP buttons, you can use the Exit menu item.

The Drafting Settings dialog box consists of three tabs:

·         Snap and Grid,

·         Polar Tracking,

·         Object Snap

·         Object snap 3D
