2D drawing in the cursor increment mode, keyboard location input, creating corners and mirroring
Drawing in the cursor increment mode
The cursor increment mode is a very convenient method of 2D drawing. Coordinates of located positions are rounded to defined values. The cursor increment mode can be set, turn on or off. During 2D location, you can access these tools from the menu started by Ctrl + right-click, or by clicking corresponding icons. If used, the increment mode is signaled in the status bar as highlighted “DX DY”. You see the exact cursor location displayed near cursor.
Consider, whether you need to display the distance from the last 2D enter or relative to the user defined coordinates origin. In this particular example, the cursor increments are set to 1 mm and displayed coordinates are X and Y distance from the previous enter.
Keyboard location input
If you need to define a 2D location as X-Y distance from the last enter, in the absolute coordinates, or at the distance and angle from the last enter, select the corresponding mode from the toolbar or from pop-up menu after pressing Ctrl + right-click.
More convenient is to use combined method of input, available also by pressing TAB key. In this example, drawing under angle is selected. Basically, you can choose drawing at fixed coordinate, length or angle. Entering two values, you define the location definitively.
Mirroring
To create the right side of the profile, the left side is mirrored. Still in the cursor increment mode, you can easily define the vertical mirror axis.
Creating a corner
Exceeding segments are cut off by creating a corner. Automatic detection of the corner is similar as in the fillet or chamfer functions.
See Creating Corners, Chamfers and Fillets.
2D drawing - single segment offsets, creating corners
Offset of a single segment, created by dragging
Another convenient method of offset creation is dragging of offset copies. If you turn on the incremental mode, offset copies are changed according to cursor movement. The offset distance is changed in defined steps. Here, the step is 1 mm and the distance is displayed near the cursor.
Creating a corner
The inner part of the profile is created as a line offset to the outline. Again, the exceeding segments are cut off by the Corner function. Another method how to cut off such segments is, for instance, trimming by a line or arc segment. After trimming the segments, the exceeding segments are cleared from display. If any other objects are lying under them, they are temporarily blanked. To fix this, redraw the display by pressing “F6” or, very easily, by turning the mouse wheel one notch forward and backward.
