Use these functions to specify the development parameters for the 3-D developments created with the Develop sheet function. Depending on the selected function, you can change:
In a drawing you can derive several developments with different parameter settings from one Sheet Metal part. The parameter settings will be saved in the development. In this way it is possible to save developments intended for DXF export, e.g. for LVD or Bystronic, with their different parameters in one drawing. After changing the Sheet Metal part, the different parameters will be taken into account when updating the development accordingly. Also, a new view will be created for each development.
The pre-setting for new drawings can be specified in the Configuration Editor at Sheet Metal > Sheet development > Default setting.
When you call the function, the following dialogue window will be displayed:
Here you specify the pre-settings for the option Sheet alignment: Automatic.
The options for the selection of direction and upper side (Direction symbol, Coated side, ...) can be changed by activating or deactivating the corresponding checkboxes . The priority results from the ascending order of the active options.
For instance, the direction symbol marks the processing direction and the processed side with a direction arrow. In this way, the development will be created from the side on which the arrow is located, and will be automatically aligned horizontally to the direction symbol.
When milling composite panels the coated side is normally located at the bottom. Use the Invert upper side option to flip the upper side to the bottom.
The Bend lines and Bend zones beneath Representation can be activated or deactivated. Length, distance to outer contour, line type and colour can be specified in the Extended settings on the Bend lines tab. Positive and negative bend lines can be configured separately.
Activate the Subordinate parts checkbox if you also want to show parts that are subordinated to a flange (e.g. welded nuts, 3-D parts).
Bend line and bend zone active
Isolated 3-D points of the Sheet Metal part can also be hidden or shown. The position of the points (in the development) refer to the flange or the bend zone that was active during creation. If the main part is active, no points will be developed.
The setting affects only the Isolated 3-D points supplied by the Sheet Metal part. Isolated points in the development that have been created subsequently are always visible.
(1) Isolated point, (1a), active sheet flange
(2) Isolated point, (2a), active sheet flange
(3) Isolated point (3a), base sheet active
If you activate the Dimension checkbox, only the greatest extension in X- and Y-direction will be dimensioned.
If you activate the Outer contour checkbox, the complete contour will be dimensioned.
If you activate the Bend lines checkbox, the bend lines running parallel to the outer contour will be dimensioned, independent of the other dimensioning settings.
If you activate the Processings checkbox, dimension chains will also be created for bores and subtractions.
Here you can configure annotations for developments (bend lines, cross-breaks, punchings). Also, you can define additional texts, e.g. for the production. You can either define the texts manually, with the help of the Annotation Editor, or load the annotations for Bystronic or LVD via the Favourites .
To start the Annotation Editor, click the icon next to the option. For each annotation, the attributes for evaluation will be displayed. These can also be supplemented by additional, user-defined comments. You can assign to each text block the properties Font, Character set, Font size, Line spacing, Font colour, Aspect ratio/Inclination (only for HiCAD fonts) and the orientation of the text (left, centred, right).
Bend line texts |
Different attributes and text properties can be assigned for positive and negative angles. This icon copies the settings of the Annotation Editor from the positive to the negative angle and vice versa. The procedure or tool selected for text creation will then be shown in the development. If you want to display the angles, you can choose between Bend angle and Aperture angle. To show the allowance method or the milling tool in the development you need to activate the attribute in the Annotation Editor. The bend line and, if required, the bend zone, can also be represented by two short lines at the start and the end of the bend edge instead of one continuous line. The representation of the bend line can be defined in the Extended settings. |
Cross-break height, |
The cross-break height and the cross-break angle can be displayed in the development. |
Punching, moulding and embossing tools |
When you activate this option, the WZNR (Tool number) column from the catalogue will also be output with the development. |
Auxiliary text |
Use this option to create an additional text which will be evaluated by the software of the sheet metal processing machine (LVD or Bystronic). If you choose Positioning: Inside/Outside, the dimensionings, the article number and, in some cases, the item number will be displayed by default. The text will be generated from the part attributes. If you choose Text with leader line, the annotation will be placed in the form of a tag with a leader line. |
Please note:
If you move the cursor over a text in the 3-D development, the text will be highlighted in magenta. If you now press and hold down the left mouse button you can move the text. When you update the development the text will be moved back to its original position.
The settings of the dialogue window can be saved as favourites and re-used at any time. To do this, click on the symbol at the bottom left of the window.
The settings for LVD, Bystronic, COBUS NCAD and Lantek Expert have been predefined and saved as Favourites.
The Favourites delivered with the software are only examples and may require adjustment to your (LVD, Bystronic etc.) machines.
More information on Favourites Management can be found in the Manage Favourites topic of the HiCAD Basics Help.
Favourites can be loaded as default settings for new drawings in the Configuration Editor at Sheet Metal > Sheet development > Default setting.
The Extended settings dialogue window consists of the following tabs:
In the upper area of the dialogue you can specify the settings for the Line colour, Line type and Layer of the different edges.
For instance, you can specify the colour, line type and layer for powder marking lines here.
You can assign different parameters to inner and outer contours. Inner contours are all contours that can be cut out of the sheet and are no standard processings. This allows you, for instance, to define the adjustment of the layers for the DXF export more accurately.
You can select different line parameters for positive and negative bend angles. For Start angle and End angle, respectively, you can specify an area of the angle for the line colour. Use the Plus icon to add further rows for new angle areas. Use the Delete icon to delete a marked row.
The development of a sheet is always a 3-D part. To exclude cross-breaks, mouldings (including punches and bore patterns) or catalogue symbols from the 3-D representation, activate the corresponding checkbox .
Fillets exceeding the maximum radius will not be marked as bend zones.
(1) No planar representation
(2) Planar representation for cross-breaks and moulding
Bend lines can also be represented as two short lines at the start and the end of a bend edge instead of one continuous line. Furthermore, you have the option to mark the start and the end by means of a punch. Here, too, you can specify different values for the positive and the negative angle.
This icon copies the settings from the positive to the negative angle and vice versa.
The milling tool path will be displayed if you have activated Bend zone checkbox beneath Representation in the Sheet development default settings dialogue. The appearance of the tool path is determined on the Milling + Folding tab of the Extended settings dialogue window that you open with a click on the symbol.
In the upper part of the dialogue you can specify the settings for Line colour, Line type and Layer of the different tool paths.
You can then specify tool-dependent line parameters for positive and negative bend angles; "milled from top" refers to the edge that you chose for Sheet alignment: Automatic (see above).
By the specification of tool-dependent settings the milling tool paths in the upper part of the dialogue may be overwritten.
The icon adds a row for a tool from the catalogue. Click the icon to delete a marked row again.
(1) Positive bend angle, milled from top, Tool V 135°
(2) Positive bend angle, milled from top, Tool V 90°
(3) Negative bend angle, milled from top, Tool V 90°
The bend line text was expanded by the Milling tool attribute by clicking the icon next to the corresponding option.
The Adjust milling tool paths for production option refers to sheet corners where three milling edge zones converge. In the development, the lines do normally not converge in a common intersection point.
Therefore you have now the option to adjust the milling lines in such a way that they end in one common point.
It is important that only the milling lines are adjusted, and not the 3-D geometry.
If there are two converging milling lines, the milling lines will be lengthened / shortened, so that they converge in a common intersection point.
For this purpose there are two parameters:
Sum to max. |
With this parameter you define corners in which several milling lines converge. The distance of the end points is pairwise smaller than the snap distance. |
Max.lateral correction |
This value defines the extent to which the new milling line may laterally deviate from the adjusted milling line. Decisive is the distance of the new end point to the original milling line. |
After confirming the settings with OK, the parameters will be applied, depending on the selected function (Individual, All or Default setting).
For the Individual function you have the option to display a Preview by clicking on the same-named button.
(1) Bend radius and bend angle with different annotation parameters
(2) Different colours for interrupted bend lines and bend zones
(3) Dimension
(4) Cross-break with red height and black angle
(5) Punch with tool number
If two flanges touch one another (without clearance) during development, a line representing a "separation cut" will be inserted into the development (see image below). If the front face of a bend zone directly touches a flange, such a separating line will be inserted here, too.
Through the merging of flanges and bend zones during a sheet development, edges that belong to the outer contour and that will be needed for blank creation can be lost. Therefore, those separating lines will be inserted, as free edges, at their position in the development.
The separating lines are inserted at positions where contour edges are identical before the merging, and where at least one of these identical edges originates from a flange.
