TYPED INPUT BOXES
All dialogue boxes are laid out so that any required typed input is completed first, the cursor is pre set, ready to type in the first input box, if you input in descending order, there is no need to move the cursor, just press the tab key to go to the box below, if you do move the cursor with the mouse, make sure the cursor is at the very start (left side) of the input box
If the box is filled in blue, just type your input in, anything already in the box will disappear automatically, if the box is white, with something in it, delete (with the delete key) anything in the box, and type in your answer.
Some boxes have validators (to ensure your input is in the acceptable range). If, say, you input too large a size, a bell will ring and an exclamation may appear when you attempt to clear the dialogue box.
Do not leave any input box blank, some boxes come with a 0, if you not need to change it, leave as 0.
Some boxes come up with a guide figure in them, which is the distance to another object (internal walls show distance to nearest wall), other have pre set numbers, some of which can be customised, so that a figure you normally use can become the start up figure - click CUSTOMISE

RADIO BUTTONS
Circle shaped , with a black dot in one, always in a group, if changing, just click your new selection, only one of the group may be chosen..

CHECK BOXES
Square boxes, unlike radio buttons, can be checked or unchecked, individually, and one or more checked in a group.

HINT You can just press the Enter key to accept the default answer button (i.e. the button that has a darker outline), instead of moving the cursor over the OK button and clicking the left mouse button, on all dialogue or message boxes in this programme
