Sheet metal

Toolbox: SYSCAD Attachment details:

Drawing of any sheet metal contour with a polyline with arbitrary wall thickness and inner and outer radius. The sheet metal contours are adjustable via double-click or via moving the grips.

Enter the parameters into this dialog box and define the first point by clicking into your drawing. It could be helpful to use OSNAP.

The coordinates of the second point can be determined by using relative coordinate input (@) or by clicking onto a point in your drawing. Define a third point afterwards to determine the direction for drawing the wall thickness of the sheet metal.

Procedure analogously to membrane.

The preferred values for radius and thickness can be defined in the dialog box SYSCAD VARIABLE in tab Attachment-Details for each sheet metal type.

Automatic dimensioning of sheet metals

Two variations are possible. Activate the command and click onto the sheet metal to be dimensioned. Move the dimensions with AutoCAD object grips if necessary.

Sheet metal sharp-edged

This command creates a sharp-edged auxiliary contour of the selected sheet metal . The so created contour can be used for easy dimensioning of the sheet metal without the object snap function "assumed intersection point". This object snap is not available anymore from AutoCAD 2007 for ARX objects consisting of polylines.

Sheet development

Using this command, you get the sheet development (outer surface) of the sheet metal with the defined length. Activate the command and click onto the sheet metal.

The outer surface (developed view) is calculated by means of the stretched lengt. The calculation with neutral axis is not used yet.

Sheet join

You can join two sheet metals. To do so, activate the function "Sheet join" and click onto the two sheet metals you want to join. The function will join those ends of the sheet metals lying near the selection points. The properties of the sheet metal chosen first are decisive and will be applied to the second sheet metal.

Fold line of sheet metals

This command automatically draws a polyline of the fold line of a sheet metal. Activate the command and click onto the sheet metal. Use the left mouse button to activate the required side of the sheet metal. Confirm your selection with a right mouse click.

Projection of sheet edges

This command automatically draws a side view or top view of a sheet metal. Activate the command and click onto the vertical elements of the sheet metal. Confirm your selection and choose the horizontal elements. To determine the length of the elevation you need to previously draw a line and select it. The projection is created afterwards.

You can change the view in SYSCAD VARIABLE / LIST and SHEET PROJECTION.

Sheet separate

To separate sheet metals activate the function "Sheet separate" , select the sheet metal and define the point for separation.

Sheet from polyline

The function "Sheet from polyline" creates sheet metals from the line segments of a polyline. .

Sheet doubling

The function "Sheet doubling" creates a sheet metal for a doubling/lamination of an existing sheet or membrane.

Enter the required distance into the following dialog box. Move the virtual displayed contour with the left mouse button to the required side of the metal sheet and confirm with a  right mouse click. Use the red arrow to draw the sheet metal contour to any side of the virtual contour. Define the sheet metal contour in the dialog box coming up now.
