Generic types ELBO and BEND have a connection reference to facilitate connections to the elbow or bend. Isodraft will always treat an elbow or bend as having an offline leg if it has a P3 with a bore greater than zero. Care is needed when selecting a symbol key and point set in order to achieve the required results. |
|
2 |
To use this symbol, the p-points must be arranged as shown in the following diagram and P3 should not have its bore set.
|
|
3 |
Replace the @ character in the symbol key with an integer (1 to 9) denoting the number of segments. |
|
4 |
Replace the + character in the symbol key with an integer (1 to 9) denoting the ratio of the bend radius to the pipe bore. |
|
5 |
The p-point for the offline connection (P3) can be positioned anywhere along the horizontal (P1) axis that suits the specific component design. |
|
6 |
Reducing elbows can have any of the end types BW, CP, FL, SC, or SW, but not PL. |
|
7 |
This type of component is treated as a fitting in the material list. |
|
8 |
This type of component is treated as tube in the material list. |
|
9 |
The dimensions of all Elbow and Bend components depend upon plotted leg length. The default plotted leg length is 9mm, but this can be set to a different value using the LEGLENGTH command. The minimum value the user can set is 6mm. |
