Footnotes

...
You will find a complete reference of all mouse functions used in SISCAD-P in the appendix on page gif.

...
Of course, you can always generate a point by directly entering its co-ordinates.

...
To open and close additional windows, use the window menu (tool box in the main menu).

...
The individual snap symbols will be explained in detail within section Construction Aids on page gif.

...
A later saving of constraints is possible by using the command REMEMBER CONSTRAINT.

...
Activating parametric mode is done by the command MODIFY PART PARM OP=<id>;PRM=1!.

...
The document SISCAD-P Parametrics will explain the significance of the degrees of freedom.

...
Both dimensioning methods are explained in detail in chapter Dimensioning page gif.

...
Info on parameterization, layers, parts are available through the corresponding icons.

...
Part lists (or Bill of materials) contain information on parts in table form. SISCAD-P offers you quantity overview part lists (QBOM), constructionally part lists (CBOM) and structure part lists (SBOM).

...
Master data is the construction data of the parts. Master data id divided into article-master data (e.g. part number, part name, material) and master data of title blocks (e.g. drawing number, company, modification). This last type of data can also be entered in the text field. Master data is managed with the help of variables in SISCAD-P

...
You are warned before SISCAD-P executes a command that cannot be undone. Undoing several commands is possible by using the Buffer Administration feature of the Tool Box.

...
The required steps to configure output devices are described in the document SISCAD-P Installation Guide.

...
More precisely, the help text always pertains to the currently marked yellow parameter of the CAD-command. The help text concerning actions, objects and characterizations is, however, always available through the right mouse button.

...
The structure of the CAD commands is looked at more closely in an appendix.

...
If you want to avoid having new auxiliary lines generated on touching certain points, you have to press the -key when touching the point you want to select. SISCAD-P will ignore all subsequent points as long as the the key remains depressed.

...
The pick symbol shows a line as opposed to pick symbol 2 (Picking a point on a line) where a point is shown in the circle.

...
You are also offered virtual intersection points.

...
Producing and modifying hatch patterns is done with the command CREATE/MODIFY HATCHING OP=<id>;HPAT=pattern! .SISCAD-P offers you more than 20 of the most usual hatching patterns. Using further optional parameters (e.g. DST = hatch pattern distance), you can additionally modify the look of the hatch patterns.

...
When generating objects with SISCAD-P, you are always offered all possible solutions. Using the optional parameter SEL , you select your solution. If this parameter is not used, all possible solutions are generated.

...
To generate an arc of circle, you use additional parameters, e.g. CIDxREFL (circle ID).

...
If a line or a circle are selected as this parameter, the resulting circle will be tangent to those objects.

...
Naturally, circles are also taken into account when trimming. We only ignore them in these exercises.

...
Because you can combine areas (UNI,DIF,ITS) , you can generate areas quickly as well as in a logical manner. Thus, you can for example unite areas and then hatch the result with only one command. To hatch areas, there is the command CREATE HATCHING.

...
After the command has terminated, you have no way to immediately see that an area has been created. The area status will only be visible once you try to combine or hatch the area.

...
You select an area by picking a border line of the area.

...
Using the parameter OPi (OPi stands for an arbitrary number of operands), you can enter as many areas as you want, and they all will be subtracted from the first area. You can additionally specify circles and closed lines as OPi.

...
When using the commands to combine areas, the display attributes (e.g. hatch pattern) of the newly generated area are always inherited from the first area selected during the creation of the new area.

...
Almost all types of dimensions (except for chain dimensions, ascending dimensions and vertical linear dimensions) can be used for parametric work.

...
To change the value of a parametric dimension, use the CAD-command MODIFY NOMINALSIZE.

...
WYSIWYG = What You See Is What You Get.

...
As the dimensions are displayed green, they all are reference dimensions.

...
The defaults are stored in the file siscadp.def. You can find further information in the document: SISCAD-P Installation Guide.

...
DXF = Data eXchange Format

...
If the execution of the teaching program is to be terminated, or another tutorial is to be started, you can reactivate this window by clicking the Load icon.

...
Some commands (e.g. MODIFY) do not need a characterization.

...
The language elements characterization and parameter are not mandatory for all CAD-commands (MODIFY,VIEW POINT).

...
That's why this symbol is also displayed in the text window for all parameters that have been clicked in the CAD-command window, and that expect a text as return value.

...
Commands can also be concluded by a right mouse click in the graphics window
