In sketch adding dimension

len_1962

Why is there no ability to do math functions in the dimension field, would really help when a drawing you are give has running dims or need 3 times or 1/2 the number. oh yes units would be nice also as some of the others do mm, in, cm, m after the number and converts to the current units being used.

@len_1962‌ This is getting a lot of attention and I have added a ticket for you. Once it is addressed, you will be notified. If there are more people that want this, you can let me know and I will add you to it.

Currently we store the units with the dimension value so that they remain in the dimension definition and can be changed. All sketch dimensions default to the units of the document at time of creation but can have different units specified. If they DO then the value shown in the sketch is, e.g. 1 but the value when you edit is 25.4mm. This is similar to how we expect math functions and equations could work, where the equation is kept around and modifiable but the shown value is the calculated one.

Alternatively/additionally, we could do a one-off calculation and store the calculated result, not the equation. Is that "one shot equation" of value if we have "full" equations?

Paul,
just need simple calculator to do the math because maybe I don't have a one handy, so in the dimension field i would type, 2.345-1.365 +.65875 hit enter and it sets the dim in the field, don't need to hold onto the equation just calculate it and done. SW does this and it is so so handy!

Ok. Understood. Thanks.

+1 for this. I use this all the time in SolidWorks

and also.... entering unit specific dimensions using a suffix modifier - for example, working in an english unit part and entering a dimension that I want to be metric instead, so why not instead of entering 5 enter 5mm and the dialog does the conversion to english automatically. t\This is a great feature and time saver in SW that I use all the time because in my product design work I'm constantly working with stock components that area mix of english and metric.
