HiCAD Sheet Metal enables you to model different sheet parts using the technology data.
The technology data includes:
Furthermore, you can create sheets from a 3-D body, from 2-D developments, from polylines and as an external offset of a 3-D body.
You can only find the Sheet Main Part function in the context menu of a sheet part of the drawing. If you choose this function, the base sheet (sheet main part) becomes active, and the context menu containing the processing functions opens. The selected function is then applied to the base sheet.
Flanges and bend zones are created as equal sub-parts of the subordinate part of the selected reference flange. This enables assemblies, which, in turn, may be grouped under a main assembly, to be handled correctly.
Each sheet main part contains specific non-graphical information, such as quantity, item number, part name, weight or dimensions. This information, which are in HiCAD referred to as part attributes, are taken into account for BOM creation.
Use the Part attributes function (right-click on sheet main part in the ICN, please also see HiCAD Basics chapter) to assign the attributes to the sheet main part.
Some part attributes can be assigned automatically, e.g. the sheet thickness, weight or the dimensions of a sheet development. For this, the files ABWPAR.DAT and ALG3PAR.DAT need to be adapted accordingly.
Sheets BOM-relevant (yes=1 , no=0) 1
Stuecklistenattribute aktualisieren ( 0=nein, 1=beim Positionieren, 2 = immer)
0 ;
[Update BOM attributes (0=no, 1=when itemising, 2=always)
0]
The calculation and taking over into the BOM takes place in mm2. Steel Engineering parts are taken over into the BOM in m2.
Synchronize item numbers/part attributes when updating file: Never, Only for sub-parts, For main parts and sub-parts
For main parts and sub-parts.
Weight calculation: Do not auto-calculate, Only when itemising, Always
Only when itemising.
The part attribute Height was formerly used for entering sheet thicknesses as part attributes. There is now a new sheet thickness attribute for this. If you want to continue to additionally specify the thickness in the Height field, please modify the SYS/ABWPAR:DAT file as follows:
Abmessungen aus Abwicklungskante (1 = §L2D,§B2D,§T2D) (2 = 1 + §02,§03,§04) (3= 1 + §04)
3
[Dimensions from development edge (1 = §L2D,§B2D,§T2D) (2 = 1 + §02,§03,§04) (3= 1 + §04)
3]
For part attributes, the surfaces of folded sheets are calculated in square millimetres. When transferred to BOMs, the values are converted into square metres.
For sheet metal processing, a special BOM configuration called HICAD_Blech*.RMS is available.

will be considered for the transfer of the part attributes to the Report Manager. This does however not apply to database BOMs.
If you decide to use a semi-finished product 
from the Catalogue Editor, the sheet thickness will not be requested, e.g. when creating a base sheet. The Sheet thickness and the Material will then be taken from the Catalogue Editor and applied to the base sheet.
The Article number is editable, even if the created sheet is generated from a semi-finished product from the catalogue. The catalogue column BZ is not necessarily linked to the article number in the part attributes; BZ can be linked to any part attribute (e.g. $01 Designation 1).
Semi-finished products can also be activated, deactivated or changed subsequently. To do this, double-click the Base sheet feature. The dialogue window for base sheet creation will be displayed. You can then activate or deactivate the Semi-finished product checkbox, or select a different semi-finished product by clicking the 
icon. Confirm with OK.
In the Catalogue Editor you can find the semi-finished products at Factory standards > Sheets. Here you can, for instance, Aluminium sheets/plates, Stainless steel sheets/plates or Bulb plates.
The Delete 
function for Sheet Metal parts can be called via
The deleting of bend zones or flanges in Sheet Metal parts with feature log is not possible!
If you activate a flange or bend zone and choose the Delete object function, the following message appears:
Flanges and bend zones cannot be deleted if the feature log is active. The complete Sheet Metal part will be deleted.
Click OK to delete the complete sheet.
Click Cancel to end the function without deleting anything.
To avoid repeated display of the message, activate the Suppress message checkbox.
If a Sheet Metal part has no feature log, the flange of bend zone will be deleted immediately, without any further queries.
The bend simulation enables the bend process to be tested visually so that faults can be identified. Processing (e.g. boring) beyond the bend zones is possible in the unfolded state and often the only production-specific modelling of the sheet construction. Automatic backbend is possible if you select the function again.
To obtain the blank (development) of the modelled Sheet Metal part, HiCAD offers you developments according to different calculation methods (allowance methods) that take the material-dependent length change of the workpiece during bending processes into account.
The bend lines, bend zones and bend angles can be displayed in the blank. Automatic part dimensioning enables a quick, user-defined variant of dimensioning.
HiCAD Sheet Metal can develop both sheet parts and 3-D parts and sheet parts from other systems.
The blank can be prepared for an NC programming system.
The system provides you with a material file. You choose the material via Settings > Basic Setting > Sheet Metal Development> Material.
You can use the Catalogue Editor (EXE/CATEDITOR.EXE) to enhance the material file as required.
Derived drawings (aka workshop drawings) showing developments, blanks with section paths and 3-D views are an essential prerequisite for an accurate work preparation and production. For the automatic creation and management of these important documents, activate the Drawing tab and select Itemisation/Detailing > Drawing derivation. You are then enabled to create Sheet Metal workshop drawings, Their creation is largely similar to the creation of Steel Engineering workshop drawings.
If you use the 3-D function Weld seam (3-D Standard > Standard Parts) for the welding on of a sheet metal main part, the weld seams will be determined for all sub-parts, and superfluous (double) powder marking lines will be removed. If a sub-part is selected for a welding, only the sub-part will be welded on.
The coating lines in sectional views of Sheet metal parts can be processed with the functions of the context menu of coating lines (right-click the coating line to open the menu). You can
Coating lines can be hidden or shown in the active view or in all sectional views. One distinguishes between coating lines on the inner side and the outer side.
If all coating lines have been hidden, the lines can be redisplayed again via the context menu for sheets: In the sectional view, right-click the sheet and choose Properties > Coating line.
