Click ok Back in the formula write the required formula using this variable (eg *50) -Click ok Close all the dialog box Now if you change value of SCALE tag and regenerate, the value of L1 will change according to the formula specified.Repeat the process for all the tags to get required value.While drafting in Auto CAD, sometimes we come to situation where we need to upadate some text based on values of other text (similar to using formulas as in excel).In such case we can use FIELDS of Autocad to do our calculations and update the drawings automatically. A sample method is given below using example of scale block: – Draw the shapes (lines, hatch etc) -Define block attributes (name them L1, R1, R2, R3, R4, R5, SCALE) (i made SCALE as hidden so that it will not be visible and will be used for calculation only) also i made all tags prompting to “DO NOT EDIT” as you will see later as these values should be updated automatically).
I’m interested to hear your thoughts no matter what environment you use them in. What do you use sketch blocks for (schematics, layouts, custom symbols etc)?
Drawing Settings can be pushed to each individual drawing's title block.
Now that you know what can be pushed lets see it in action. Attributes, a mapping, and project description labels.
Here are a few tips and rules of thumb for attributes. They store information yet that info is not visible on the drawing. It is entered on each symbol but never shows on the drawing. selecting one of the grips allows the attribute to be moved independent of the symbol. This isn't necessary for the Automatic Title Block update.
Because attributes can be modified per block instance, modifying attributes in existing blocks can be confusing.
