# Flowsheet

The Flowsheet can be operated in any one of three modes: 1. Free format. 2. With an Ortho Snap. 3. With an Iso Snap. Coupled with these options the user has control of the scale of the flowsheet (zoom) and the grid characteristic. The snap and scale settings are saved with each flowsheet so that you can work in different modes in different flowsheets. It is possible to change modes at any time, although this is not recommended if you wish to retain a consistent layout of elements. Each mode is selected by toggling either of the two buttons on the flowsheet toolbar: If the button is highlighted, then the corresponding mode is selected, if neither button is highlighted then free format is selected. Scale and grid settings and visibility are made from the two drop-down options on the upper toolbar: The left drop-down provides the scale of the flowsheet; the right drop down allows you to show no grid, a fine grid or a coarse grid. (In Free Format mode this setting is ignored). The presentation of the Flowsheet can also be changed based on your personal preferences. To access the Global settings for the Flowsheet, select Options | Flowsheet and the Flowsheet Options dialog will be displayed as per Figure 1 & 2. Figure 1: Flowsheet Options - General. Scale, Grid and Snap Options can be pre-set here but subsequently altered using the toolbar or the flowsheet toolbar. The displayed background color of the flowsheet is white by default however, this can also be changed from here. Split Pipe on Insertion: This determines the effect of joining a new pipe to an existing pipe to create a tee or adding a component to a pipe such as a valve. Either the pipe will split in two equal lengths, each length having the same properties as the original pipe or the original length will be retained and a new pipe added - the new pipe copied from the default setting. Always Create Backup File: This is checked OFF by default. When checked ON, this enables you to set up the software to create a backup file of your model. Figure 2: Flowsheet Options - Components.
