Description
Work in progress. It works for me. Tell me if anything is wrong.
Macro which, with a simple click on a spreadsheet cell, adds a length constraint to a line or between 2 points using a spreadsheet cell alias or address (ex. C2). Future changes to the spreadsheet will update the constraint.
Just select 1 line, 2 points or a constraint, click on a spreadsheet cell and run the macro. You can select lines, points at the ends of a line, points, circle, arc of circle.
Usage
1) Select:
- a line,
- two points (end of a line, center of a circle, etc.)
- or a length constraint
2) Click on a spreadsheet cell, with or without an alias, that has a numerical value:
3) Run the macro.
4) Select the desired type of constraint:
If the cell has an alias, the length property of the constraint will be something like 'Spreadsheet.alias'. Otherwise, something like 'Spreadsheet.D4'.
5) If the constraint causes a conflict in the sketch and the "conflict detection" box is checked, the macro will offer to delete the new constraint:
If you select an existing constraint, you can change the value for a cell in the spreadsheet:
To make things even more refined, if, for example, a line is horizontal rather than vertical, when the dialogue box opens, the focus will be on the button for imposing a horizontal constraint. If the line is vertical rather than horizontal, the focus will be on the button to impose a vertical constraint. In both cases, simply press the enter key if you are happy with this choice.
