View payout path

HelpCadfil Help contents Home

The payout path, previously generated, can be viewed by selecting the View Payout Path option at the main menu. The viewing section enables the user to view from any direction the component and one of its relevant payout path tracks. The payout path is shown as a series of payout eye points, connected by lines. This permits the user to view the motion of the payout eye relative to the mandrel. The system requests the user to input the name of the existing payout path file. The system will then read the path and mandrel data. If payout viewing has been entered automatically (from say a QuickCAD) payout data is already loaded.

The dialog (as below) is then shown, the options are as follows:

Viewing Dialog

View OptionsThis allows the user to select different view directions, to select graphics output to a printer, and to use the zoom and pan facilities. The use of this menu is as described in the section on fibre path viewing.

Step Switching the step option allows the path to be redrawn in steps or stages. The next section is drawn by clicking the step increment. This is a useful option for enabling the operator to view the progress of the eye around the mandrel, when winding the selected path.

Rotate X Axis This option enables the user to rotate the payout eye path around the component, the X axis being the components and the paths axis of revolution. This path rotation can be carried out in any view. On selecting this option the user is prompted, ENTER RELATIVE X AXIS ROTATION >. The payout path will be drawn in its new position (either in full or in steps), the path in its initial position remaining displayed, i.e.. two paths will be visible, the original and its new rotated location.

DRAW This option clears the graphics window and redraws with current settings.

The following options determine what is drawn at the next redraw.

Fibre Bands This allows the user to see the band structure

Fpath+Pmark Draws the Fibre Path and Payout Markers for the payout points.

Ppath+Pmark Draws the Payout Path with Payout Markers on it.

2D Pay Path Draws the Payout Path with the points rotated into a common plane

F>P Lines Draws lines (representing the fibre) from the mandrel to the payout point. These data is as it would be seen on a 4-axis machine (DEFAULT MODE)

Animate Static It is possible for the user to create a solid model representation of the fibre dispensing head using a number cylindrical and cuboid (brick) primitives. In this mode the user can draw each position of the payout head around the mandrel for a particular payout path. The payout block and mandrel are either draw in wire-frame or solid dependant on the SHADE mode. The head is rotated for the rotating eye and yaw axes. The fibre band is also drawn from the payout head to the mandrel. The band can be given a particular width and the effects of band twist can be observed. If this option (or Animate Dynamic) is selected the user will be asked to specify the post process type so that the animation can show the machine motions for different post process options. Post process options are discussed in a later section of this manual.

Animate Dynamic This is similar to Animate Static The head is successively draw and then removed as the payout program is stepped through. This takes the form of an animation to visually see the head moving around the mandrel.

Pick Display Points The system goes into the Animate Static mode but the user is asked to enter the point number(s) of a particular payout position(s). The user may have identified a particular point(s) of interest perhaps for graphics output. Using this option the user can display the payout head for the chosen position. The mandrel and head are drawn using the current view options (e.g. SHADE mode, VIEW and ZOOM scale).

EXIT This option returns control to the previous menu, if you need to adjust the window positions or sizes or need to make a screen grab and do not want the views dialog in the view. The dialog can be reopened from the menu options at the to of the screen.

QUIT The quit option available on payout viewing closes the dialog and exits from the payout viewing section of Cadfil, for example if you wish to proceed to post-processing.
