Construction parameter x value

The application of the construction parameter x value and the resulting manifold styling options is one of the outstanding features of Grafis. The application of x values facilitates the creation of style variations or trend adaptation simply through subsequent alteration of the x values. The interactive constructions and tools contain a large number of x values and thus, remain modifiable at a later time.

X values are size-dependent construction parameters. Their numerical values are logged in x value list and can represent lengths, distances, radius or angles, for example. X values can be altered after completion of a style at any time. Thus, very effective subsequent modification of the style is possible.

There are three different types of x values:

  • x values of the construction record,
  • the x values of all parts (global x values) and
  • the x values of non-interactive basic construction which have been programmed in the Grafis Programming Language.

These difference relate to the area of validity of the respective x value type. The application of x values is identical for all types and is elaborated on the x values of the construction record.

The x values of the interactive constructions can only be edited in the drag environment and are greyed out in the x value list.
Step-by-step guide
  • Open the list of x values from the pull-down menu Extras via x value list...or from Control barx value list .
  • Select the list: (global or active piece)
  • Select the index card values of the part
  • enter and edit size-dependent x value

X values of the construction record

The x values of the construction record are user defined and implemented during construction. Thus, the respective construction step can be altered later.

Before starting the construction consider for which construction steps the use of x values would be beneficial for flexible pattern modification!

x values of the part can be used for example:

  • for control of applied interactive tools via the x value list
  • for co-ordinates within a part, e.g. position of a yoke in front and back

X values of all parts (global x values)

Global x values apply to all parts of the style. They can be used for example for:

  • seam allowance self / lining,
  • ease which is to be applied to different parts of the style,
  • distances for markings,
  • adaptation factors for stretch etc.
The x values of all parts are additionally indicated with a G (for ‘global’); small and capital letters have the same significance. Example: XG5 or xg5.

XG5 stands for the fifth x value of the x value list of all parts whereas x5 stands for the fifth x value of the construction record of the active part. This rule applies to calculation with z values as well as direct entry into numerical fields.

X values of the basic blocks

Each basic block contains a prepared x value list. The x values represent lengths, percent, or angles which are variable according to the respective construction instruction, e.g. ease or position and length of the darts. The implementation of the x value into the basic block and pre-assignment of an appropriate value has been done by the developer of the basic block already. The user has the option to modify the basic block to his own requirements by altering the x values.

Opening new x values or deleting existing x values is not possible with x values of the basic block.

The x value window

The X values dialogue offers the following display options for display of the required x value table.

Insert new x value into the x value list:

  • Control bar → x value list
  • Select the List: (active part or global)
  • for active part: select the index card values of the part
  • click on add new x value; a maximum of 80 x values can be opened per part.
  • double-click the comment line and enter the description for the new x value. Be careful to use clear definitions!
  • enter the standard value in the standard value column and <ENTER>
  • possibly: insert size-related x value entries into the columns for existing sizes
  • if required: delete the last x value with delete last x value
  • end with exit

Continue the construction and enter an x value (e.g.: X02 oder X0G1) instead of a numerical value

List and index cards:

For each part, one of the following x value tables can be displayed:

  • global (the x values of all parts) or
  • x values of the active part The index cards contain the x values of the non-interactive basic blocks and the x values of the construction record.

Select the required list by clicking on the index card tab. The x value list of the interactive constructions remains greyed out.

Generate new x value and apply it to the construction

Generate a new style and call the Last and in another part the Basic shoe . Inherit the lines in another part.

Open the x value list of the construction record via Control bar → x value list and select active part The file card active part is active.

Open by clicking on Add new X value X values for the strap width, the strap width for the first strap, the strap distance, and the strap width for the second strap. Set the default value of x1 to 18 mm, x2 to 20 mm, x3 to 5 mm, and x4 to 25 mm. Construct a parallel to the upper shaft entry with x1 using Parallele. Construct a parallel to the bale line with x2 and a parallel to this parallel with the X value for the strap distance x3. You construct another parallel for the second strap with x4.

Change the X value and start a test run. Save the style as 'Exercise sandal 2".

Alterations to x values are only visible after test run and grade active part . An x value must be defined before it can be used in a construction step. Should this not be the case, Grafis will refuse processing.
Whether an x value is interpreted in mm, in percent or in degrees depends on the function with which the x value is used. When entering the x value as a relative length, the x value is used as a percentage. When entering the x value as a rotation angle, the x value is an angle in degrees.

Redirecting an x value

x values of the record can be redirected to global x values. The character set in the comment line of the respective x value is supplemented with =>{XG4}, here for the redirection to the fourth global x value. If this character set is removed, the original values apply. The production patterns of Grafis pockets contain x values for seam allowance. If you control the seam allowance for your styles via the global x value XG02, for example, you can supplement the comment line of the seam allowance x value in the production pattern of the pocket with the character set =>{XG2}.
