Sketching a Single Item
Sketching a Single Item
There are many ways in PRIMER to sketch items. For example
- sketch function available to each keyword
- sketch off object menu
- sketch on drop-down available in many contexts
- quick-pick sketch using id key in
If a single item is being sketched this will be done according to the sketch options under Display.
By default the following actions will be taken in addition to the previous sketch function. These options may be switched off.
Draws crosshairs centred on the sketched item. This is particularly useful if the item is very small and the normal sketch cannot easily be seen. If the item is off screen a warning is given in the dialogue box.
This option will not apply if the user has pressed CN in the view control panel. Otherwise, the centre of rotation/zoom will be set to match the cross-hairs if the sketched item is on screen. The option will automatically activate if an off screen item is brought into view and similarly de-activate if an on screen item is moved out of view. Pressing will unset the centre.
This will label the sketched item in the form Mn/Sn.
This will label the nodes for some items if the zoom is deemed sufficient to show them.
Press of Delete key or redraw by using Li/Hi/Sh will remove the cross-hair, clear the sketching and unset the CN.
If you sketch multiple items simultaneously, PRIMER will work as before and only apply a sketch.
If a cross-hair unexpectedly does not appear when sketching from object menu, it is most likely that more than one item is selected. Try clearing the selection with and then reselecting.
