Multiple Extend Upwards (Feature 193)

The program allows you to extend your walls upwards in stages, that is, extend walls up through a more limited number of levels than to the top of the building. However, in order to maintain a closed envelope, you must always extend the walls through at least one level and cannot build a level from scratch.

For example, for a five storey structure, you can make a floor plan, extend to floor 2, then be on floor 3, make a floor plan, extend only to floor 3 (that is, not at all) , then make another floor plan, and extend it from level 4 to 5. Unlike the current operation, the level indicator in the data bar is active during this process to allow you to do this.

Level Inputs

Two inputs, one to show the level that you are on and one to show the level that you are copying it up to, that is the range of levels. The levels are called Current level and Extend to. The Current Level input is always disabled and is there to show you the range. Once the process is complete, it becomes enabled to select levels and Extend to disappears.

Operation

If you choose an intermediate storey, or don’t extend at all by selecting the same storey, then press extend, the program then

• extends to the level selected,
• creates a new floor plan from the blocks for the next unextended level,
• Sets the current level to the next unextended level
• Sets the in Extend to to the highest level,
• outputs a prompt explaining how to proceed

If you extend to a level that is one below the highest level, the program in fact extends to the highest level and copies the next-to-highest level to that level.

Undo and Redo

The Undo and Redo commands are active during this process and allow you to go back and try again if you have made a mistake.
