These parameters apply only to selected objects that are Column objects.
Column object has a start base, two edges, end base and optional inner segments
(A) is column starting point. It lays on the first edge(1). (B) is end point, it lays on the second edge (2). (C) is start base, (D) is end base. (S) is optional inner segment. Column may contain any number of inner segments. Arrow (E) indicates direction of currently selected element.
Column objects can be filled with stitches in two different ways:
Column object filled with zig-zag samples
Sample is the zig-zag stitch pattern that fills the Column object. Stitch samples differ in number of stitches and their layout.
Spacing parameter defines the maximum distance between stitch samples. If the Column object forms a bend, the distance on the inner curve is lower.
Auto Shortening is function that shortens some stitches on inner side of bend object to prevent too high density (see below picture).
Circles in above illustration indicate automatically shortened stitches in sharp curve
Auto Select Underlay check box allows user to switch off the automatic program decision on what type of underlay will be used for the object.
Center, Edge and Zig-Zag check boxes allow user to choose which underlays will be used for the object. More detail about offset of Edge and Zig-Zag underlay is available in the Parameters - Whole Design chapter.
(A) is object shape, (B) is edge underlay, (C) is zig-zag underlay, (D) is center underlay.
Spacing parameter indicates the spacing of the zig-zag underlay.
Make Cover Stitches allows user to switch off cover stitches. Turn off the cover stitches if you need to add only the underlay to design digitized in other software.
Auto Corners . Studio automatically splits or folds too sharp corners on Column objects. Use this check box to turn off this function.
Normal corner and automatically adjusted corners.
Perpendicular Stitches function automatically divides long columns with line (not curve) edges to two or three parts to make middle part of column perpendicular to its virtual axis.
Top : normal stitch flow from start base to end base. Bottom : middle stitches forced to perpendicular orientation
Note : Column can be followed by a Carving object which gives additional stitch texture to the column.
Pull Compensation is extension of each stitch on edge of object in order to compensate for thread pull (on elastic fabric) or sinkage (on fleece). The thread pull causes the ends of stitches are pulled inwards and object is smaller (narrower) than intended.
Max. Random Broadening defines maximum random prolongation of column stitches to side. #1 parameter applies to first edge of column and #2 to second. Random Broadening adds 'ragged edges' effect to objects.
Envelope shortens some column stitches to create special effects. When using Envelope, turn off all underlays.
Column side-to-side stitches trimmed with envelope
Gradient affects the distance between stitches within object. Distance will gradate from spacing value to spacing plus gradient value. Gradient Type combo box allows to choose from various gradation schemes.
Increasing sample spacing creates density gradient
Strips fill the column object from one side to the other, with stitches running along the column edges.
Number parameter defines number of strips.
Min. Length and Max. Length define minimum and maximum length of stitches. Length of stitches is adjusted automatically to ensure smooth approximation of curved parts of the strips.
