FILLET

Purpose:

To create fillets with corresponding trimming, between segments in 2-D drawings.

(See also Insert > FILLET for fillet only operations)

Instructions:

1. In the Modify menu, click Trim, then Fillet.

2. The system will assume the fillet type, in this mode of operation, that was last used during the connect session and, via a simple table on the screen, request from the user the relevant dimension. The system will then display in the upper left-hand side of the screen the three basic fillet geometry options that are available. With the aid of the cursor and clicking the left button on the mouse, the required fillet geometry can be selected. The system presents the user with the table in which to enter, via the keyboard, the required dimension for the type of fillet selected.

3. The user should position the cursor very close to, and within, the corner between the two segments lines where the fillet is to be created. Following a single click of the left button the system will create the required fillet between the two segments and completely trim away the remaining segments of both contours that are not connected to the fillet.

4. If the segments are two lines and stop short of one another and do not actually intersect, then the system will still try to find the one quadrant that would be bounded by the two lines if they were to be extended towards the point of theoretical intersection, however the process still requires the cursor to be positioned close to the theoretical intersection point. The system will create the fillet and automatically extend the lines until they connect to the fillet.

5. The system will fail if there is another entity, particularly an arc, which would be between the fillet and the corner point.

Options:

There are no options, except for indication mode, within this process.

Result:

A fillet will be created, and the relevant segments trimmed or straight lines extended if so required, displayed on the screen and stored in the drawing file. The color of the fillet will be black and the line type will be solid.
