Changing Lateral Sizes in a Spray Irrigation Block
Posted: Wed Apr 07, 2010 4:19 pm
Connected Spray Irrigation Blocks
After the design process, if you have selected 2 or more lateral sizes in the Zone Design Configuration table (Design|Zone Design Configuration) you may have telescoping lateral sizes in a connected Spray Irrigation Block (that is, the "Connected" option is checked) and wish to change one or more of the lateral sizes, do the following:
1. Draw a normal sprayline (Zone|Sprayline) with the same pipe size as the laterals in the block you wish to change, somewhere on the plan outside of the blocks - that is, if you have 13mm as a lateral size in your blocks, draw a 13mm connected sprayline on the plan outside of the blocks. Note it will be easier if you have the same outlet, nozzle, spacing and pressure as your sprayline irrigation blocks.
2. Select all the blocks that require changing by using Tools|Select options as required (e.g Select|Lasso, Select|Window etc).
3. Use Tools|Change Type and click on the sprayline you have just drawn as a representative outside the blocks.
4. In the dialog change the lateral pipe size to the size you wish to change the laterals to e.g 16mm. Click OK.
5. Check the correct Match and Change options e.g. Match Pipe and Change Pipe.
Note if you have not drawn your representative sprayline with the same outlet, nozzle, spacing or pressure, make sure these options are not Matched or Changed. Click OK.
6. Your existing lateral size e.g 13mm will now have changed to the new size you selected e.g 16mm.
7. Repeat for each size you wish to change.
Unconnected Spray Irrigation Blocks
In an unconnected spray irrigation block, because the laterals once placed become separate pipe and sprinklers, IRRICAD will select as many pipes sizes as it needs to during the design process and you may have several sizes down the lateral.
For those of you who have telescoping lateral sizes in an unconnected spray irrigation blocks (that is, the "Connected" check box is unchecked) and wish to change one or more of the lateral sizes, do the following:
1. Draw a normal pipe (Zone|Pipe) with the same pipe size as the laterals in the block you wish to change, somewhere on the plan outside of the blocks - that is, if you have 20mm as a lateral size in your blocks, draw a 20mm pipe on the plan outside of the blocks.
2. Select all the blocks that require changing by using Tools|Select options as required (e.g Select|Lasso, Select|Window etc).
3. Use Tools|Change Type and click on the pipe you have just drawn as a representative outside the blocks.
4. In the dialog change the lateral pipe size to the size you wish to change the laterals to e.g 25mm. Click OK.
5. Check the correct Match and Change options e.g. Match Pipe and Change Pipe. Click OK.
6. Your existing lateral size e.g 20mm will now have changed to the new size you selected e.g 25mm.

Draw a normal sprayline (Zone|Sprayline) with the same pipe size as the laterals in the block you wish to change, somewhere on the plan outside of the blocks - that is, if you have 13mm as a lateral size in your blocks, draw a 13mm connected sprayline on the plan outside of the blocks. Note it will be easier if you have the same outlet, nozzle, spacing and pressure as your sprayline irrigation blocks.
