Contents of help facility The help topics are divided into five categories. Each category is represented by a button in the help contents window. The following table provides an overview of the information available in the individual categories.
2.6 Dacs739 tutorial This practical tutorial allows you to familiarize yourself with the Dacs739 software within a very short time. It covers all the basic steps that must be carried out for the creation and archiving of your own individual contours. The tutorial includes additional information on any given topic and indicates, where the respective chapter can be found in the online help facility of Dacs739. Dacs739 support multi-tasking so that several documents can be processed simultaneously. 2.6.
Additional information For more information, click the object you would like to know more about in the diagram. Import of background pictures Depending on the application, (waistband extension or flap), a background picture can be imported. This background picture is very helpful for the entry of the seam contour. – Open “File > HPGL import”. – Select a file: flap_pattern.plt for the entry of a flap pattern bottom seam start/end or waist-band_pattern.plt for the entry of a waistband extension.
Entry of the seam contour The following exercise introduces you to the entry of a seam contour for a curved flap. The seam contour is entered as a line, i.e. the starting point of a segment corresponds to the end point of the preceding segment. When a segment is deleted, its starting point becomes the starting point of the following segment. When a segment is inserted, the next existing segment is divided into two segments of straight lines.
Drawing of first seam segment – – – – – In the toolbar, select the “Drawing” icon for lines. Drag the mouse pointer to the first coordinate for the starting point of the flap (X = 50/ Y = 50). The coordinates are displayed in the status bar. Click the left mouse button. The starting coordinate is entered. Drag the mouse pointer vertically upwards to point X = 50/ Y = 85. Click the left mouse button. The ending coordinate is entered.
– – Click the “Style” menu. Select the listbox for the type of line and select “Continuous line”. Note Use a continuous line for seam segments to be sewed and a “Dotted line” for seam segments that are not to be sewed. – – Click the “Sewing options” menu. Activate the “Segment is sewed” option in the dialog. Note In the “Sewing options” dialog, a reduced sewing speed or a reduced stitch length can be assigned to selected seam segments (see also “Seam properties”, page 44).
Drawing of second seam segment (curve) – – – – – – – Select the icon for curve in the “Drawing” toolbar. Drag the mouse pointer to the end point of the preceding line (X = 50/ Y = 85). Click the left mouse button. The starting coordinate is entered. Drag the mouse pointer to the upper right point X = 60/ Y = 95. Click the left mouse button. The ending coordinate is entered. Drag the mouse to the left to point X = 58/ Y = 95. The radius of the circle is generated. Click the left mouse button.
Seam segment properties – In the tree structure, click the arc. – Click the right mouse button (or double-click the left mouse button) and activate the “Properties” menu. If necessary, correct the coordinates in the “Arc” menu. – Check the settings for “Style” and “Sewing options”.
Drawing of next seam segment – – – – – – Drag the mouse pointer to the end point of the arc (X = 60/ Y = 95). Click the left mouse button. The starting coordinate is entered. Drag the mouse pointer to the upper right point X = 95/ Y = 102. Click the left mouse button. The ending coordinate is entered. Drag the mouse to the left to the point X = 78/ Y = 95. The radius of the circle is generated. Click the left mouse button. The ending coordinate is entered.
Arcs 4 and 5 – Enter the coordinates for the next two arcs of the flap. Arc 4 Starting point X = 105/ Y = 102 End point X = 140/ Y = 95 Radius X = 125/ Y = 95 Arc 5 Starting point X = 140/ Y = 95 End point X = 150/ Y = 85 Radius X = 150/ Y = 87.
Drawing of last seam segment – – Select the icon for line in the “Drawing” toolbar. Enter the coordinates for the last line of the flap. Line 6 Starting point X = 150/ Y = 85 End point X = 150/ Y = 50 The drawing of the flap is completed. All seam segments are individually displayed in the tree structure. Every individual seam segment can be modified at any later stage.
Seam properties – – In the tree structure, click “Seam”. Click the right mouse button. The “Seam properties” dialog is displayed. – Enter the desired values for the seam. The following values are available: Stitch length: 1.0 to 4.0 mm. Suction delay: 0% to 93 %, in steps Speed: 200 to 4000 r.p.m. Reduced speed: 200 to 4000 r.p.m. Limited speed: 200 to 4000 r.p.m. – Click “Seam start”. – Activate a “Stitch condensation” with a stitch length of 0.5 mm and 6 stitches.
Generation of mirrored seam segments or flaps For symmetrical seam courses, you have the option to mirror individual seam segments to a centred line. The second half of a symmetrical seam curve can thus be generated with ease. If a diagonal flap has been entered, the entire flap can be mirrored. Calculation of seam template The seam template is calculated automatically by the system. You have however the option to subsequently modify the template.
Calculation of fullness contour The fullness contour is also calculated automatically by the system. You have the option to subsequently modify the template. Select “Objects > Calculate fullness template” from the menu bar. The template is calculated and displayed in the CAD window. The individual segments of the pattern are added to the tree structure. File properties For every document, you have the option to save additional information. This simplifies the file management.
Data transfer to the transponder Seam contours, material clamp contours and fullness contours can be transferred individually to the transponder in the “Material clamp zero point” gauge. The “Material clamp zero point” gauge is included in the delivery. You have thus the option to transfer individual contours to the stitching plate, where they can be controlled and processed. – – – – Connect the transponder to your PC see operating instructions of the transponder).
Sample flaps and waistband extensions In the “Documents” inventory of Dacs software, various sample files for flaps and waistband extensions are saved. These samples can be modified. Caution! Prior to modification, save the sample files under a different name. Congratulations! You have reached the end of this tutorial. Please remember that more information on all topics is available from the online help.
