Controls whether skewed pipe sections are drawn with box or triangle skew depiction on the isometric drawing, and defines the form of skew dimensioning. A secondary option allows the selection of a mixture of 2D skew triangles and 3D skew boxes. Skew dimensioning offers the following options:
-
Normal dimensioning format with witness lines and so forth.
-
Simplified form when using skew triangle format; that is, the actual dimensions are positioned along the triangle sides with no witness lines.
Switch Settings
The following settings are available for Option Switch 99:
SWITCH POSITION 1, 2 & 3 - Skew Depiction Style Plus Dimension Style
|
0 |
Depict skew box with normal dimensioning. The dimension line standout is as per Option Switch 8. This is the default setting. |
|
1 |
Depict skew triangle with normal dimensioning. The dimension line position is as per Option Switch 8. |
|
2 |
Depict skew triangle with normal dimensioning. The dimension line position is as per Option Switch 100. |
|
3 |
Depict skew triangle with alternative dimensioning. Actual dimensions are positioned close to the sides of the triangle with no witness lines. Dimensions are positioned in relation to the triangle as set in Option Switch 100. |
SWITCH POSITION 2 - Mixture of 3D Boxes and 2D Triangles
|
0 |
Set all skew indications as set in Switch Position 1. |
|
1 |
Set a mixture of skew indication types: 3D skews indicated with boxes, and 2D skews indicated with triangles. |
SWITCH POSITION 3 - Skew Angles
|
0 |
Do not show skew angles. |
|
1 |
Show single skew angle on one corner with arrowheads on the arc radius. |
|
2 |
Show single skew angle on one corner without arrowheads on the arc radius. |
|
3 |
Show two skew angles on both corners with arrowheads on the arc radius. |
|
4 |
Show two skew angles on both corners without arrowheads on the arc radius. |
|
|
To use this facility, select triangle depiction of the skewed section. That is, set
position 1 of Option Switch 99 to 1, 2, or 3. If skew box depiction is selected, then
no skew angles will be output.
SWITCH POSITION 4 - Skew Angles - Right Angle Indication
|
0 |
Do not show right angle indicators on skew triangles. |
|
1 |
Output right angle indicators on skew triangles. |
