3 .4 Deleting objects

The delete menu

The delete menu is activated via Basic menu | delete. Single objects (points, lines/curves, hatching, texts) can be deleted by clicking; several objects within a rectangle to be drawn up can be deleted in one operation.

Step-by-step guide

  • Activate the object type to be deleted under the required option (single or rectangle)

  • Click the objects or draw up rec-tangle

3 .5 Parallels

Application of parallels

Parallels are significant for the construction of

  • overlap and button catch

  • turn-ups on jackets, coats and trousers

  • seam allowances and hem and others.

Step-by-step guide

  • Select distance or enter special distance value in the line d=..........

  • Activate or deactivate chain

  • Select +/-copy

  • Click the line/curve to which a parallel is to be generated.

Determine distance value

If the required distance (in millimetres) is given in the menu with d: ..... click the respective line. Otherwise a specific value has to be entered in d= .....

by clicking, entry and <ENTER>. The point is the decimal sign.

An entered distance value can be reactivated by clicking the line “^^^^^“ below d=......

Significance of chain and +/-copy

If chain is active (highlighted in blue) the parallel is generated not for the clicked line/curve, only but for all connected lines and curves. Clicking chain activates or deactivates this option.

The switch +/-copy determines whether the original line remains existent (+copy) or not existent (-copy). Toggle by clicking the line.

3.6 Corners

The construction of corners ensues with the corners menu from the basic menu. This menu contains the functions corner, straight line, curve and circle as well as various interactive corner tools, which can be called via the tools button.

As a rule, the corner function is used. The corner functions straight line, curve and circle can be constructed more comfortably with the interactive tools.

Self assessment questions

  1. What is the meaning and purpose of the construction record?

  2. What characteristics function keys have?

  3. How to delete objects?

  4. How to create parallels?

  5. How to create corners?

Easy line functions

4.1 Linking lines

4.2 Raster

4.3 Lengthening and shortening lines

4.4 Cut and separate lines

4.1 Linking lines

T he link menu

The link menu is opened from the basic menu. It allows for the linking of lines or the joining of lines by a curve.

Linking lines (connect with each other)

Step-by step guide

  • Activate the option single or chain

  • Click the lines to be linked following the right principle

  • Correction (several possible) by clicking reset

  • Terminate linking with deposit

4.2 Raster

The raster menu offers five different functions for the construction of point sequences plus the interactive tool Raster 10. The point sequences are generated along a line. The function line is the reverse function for the functions raster 0 to raster 4. The function line returns a connected point sequence back to a line.

raster 1

This function constructs a number of points with the same distance along a line.

raster 2

With raster 2 points with a pre-set distance d =... are constructed along a line. The distance is corrected by Grafis so that the points have the same distance from beginning to end

raster 3

The interactive tool Raster 10 replaces the raster 3 function completely.

raster 4

raster 4 distributes a number of points N=... evenly between two constructed points. First the number of points N=... is to be entered and the line is to be clicked.

Line

The line function is the reverse function to the raster functions. Activating line and clicking a point sequence creates a line from the point sequence. Here, also the +/- copy switch applies.
