Hooks

Being 180 hooks more difficult to draw than 90 or 135, an extra menu option has been created for them.

Once you have finished creating a piece, you can add 180 hooks to it.

To do that first click on either the beginning or the end of the piece. A small circle tells you it has been selected.

Choose Member->Add 180 Hook to selected piece.

Click with the left button of the mouse on the point where you wish the hook to end.

You see a 180 hook has been drawn.

If you select Member->Add 180 Hook to selected piece, with Aux. Measurement instead, then an Aux. Measurement will also be drawn. A box appears so you can decide the type of Aux. Measurement:

You can move the Aux. Measurement as has been explained in previous chapters if you think of a better position for it.

Once you have created the hook, if you want it to automatically calculate from the standard hook lengths you have to do something else. The following applies not only to 180 hooks:

Press F2 or choose Drawing->Toggle: WORK with ITEM / MEMBER / VALUE until "VALUE" is included in the window caption.

Now we are in the value setting; Select the value representing the hook length by clicking on it. On the window caption you can read:

Choose Drawing->Change Properties of Current Item/Member/Value or press Enter.

Now you see a window with the properties of this value.

In the field Calculated field you can type one of the following:

Press OK.

You can also make auxiliary measurements representing J or H dimensions calculated from standard hook dimensions. To do that select the appropriate value representing the J or H dimension, choose Drawing->Change Properties of Current Item/Member/Value or press Enter, and in the field Calculated field type one of the following:

Press OK.

You can have a look at models with calculated hooks included in the initial collection (there are many), to see how these macros are used in the field Calculated field on the properties window of the values representing hook dimensions. Notice that when there are hooks on both ends, only the first is calculated using these macros, whereas the last hook is calculated from the first hook. Of course this is not necessary, but this way, if the user changes the first hook, this change is inherited by the last hook.
