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 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. 
This switch position does not apply if the skew box depiction is used.
