... about Templot menu item. If not, what happens when you press the F10 key? What exactly do you see? The F10 key is used by Windows as an alternative to ALT to activate the menu system in some programs, so Templot has to over-ride this to make F10 work in Templot. If it's not working on your system, you can get to the swell mouse action by means of the menus instead. Click the action> mouse actions: geometry> swell curving radius menu item, like this: f10_menu.png All the mouse actions can be accessed via the menus in a similar way, if there is a problem with the F keys on your computer. But it is much faster to use the keyboard if possible. There is a handy chart to place behind the keyboard which you can print out by going to the help> print F key chart menu item. If you are not sure about using the mouse actions in Templot, click this link to see the mouse action notes. regards, Martin. posted: 24 Aug ...
