i have a need to change some dims but upon double clicking the dims i just get the dialogue box with the dims greyed outand cant make any changes .
Are you in an active sketch when you're trying to do this? And if yes, are the dimensions you're trying to edit in this active sketch?
It could be the dimension is driven. Pick on it and go to the "other" tab and see if either of these checkboxes are populated:
It could also be that you created the dimension as a reference dimension or if it's a sketch dimension, that the sketch is unresovled so that the dimension can't be edited
i know now what the problem is.
i drew a rectangle and dimed it but cant double click to change the dims.
i then drew the same rectangle using just continuous lines and dimed it and i can double click to change the dims.
so why the difference ?
i have been caught out by this before and easy to forget when working away .
it comes and goes ,some times it works with a rectangle and lines ,then other times it refuses to work with either .
scratching my head over this one....
its capricious ..baffled
i just did 10 sketches of a rectangle one after the other in quick sussesion ,and the dims seem to be fixed and wont work with the double click .
all i get is a dimensions dialogue box with the dimension greyed out when i double click .so i cant change it .
is there a check box somewhere that constrains the double click from working?
it did work sometimes testerday when i was doing the double click but not all the time on every seperate sketch i tried as an experiment
i have found out the problem.
i wasnt aware there are 2 ways to do a smart dimension.
if i go from the toolbar and do a smart dim ' its a driven dim' whos value cant be changed, but if i take the smart dim route from a RMB
and choose a smart dim via that route then i get a value which can be changed with a double click .
its news to me .......
how do i configure smart dims to do NON driven dims or change driven dims so i can change the numbers ?
Smart Dimensions should be editable unless the dimension is already pre-determined (driven) by other dimensions or relations. If the dimension is driven, then you can right-click on it and un-check "Driven" in the drop-down, but that will cause errors.
the topic is bigger than i thought ,now i am mired in doubt about Dimensions ,Smart dimensions and Dimexpert .is there a good appraisal to read about this topic that gives a good overview ?
then theres dims on the model or the drawing ? let alone driven dims as well ..
the |Bible¬ appears to indicate its a complicated topic as well ...
Can you post a file that's giving you trouble? (Click on "Use advanced editor" at top right to post a file.) I'm afraid I really can't understand why you're having this much trouble with dimensioning.
its pretty simple really.
i draw a rectangle
i then draw a couple of holes at each end
then i use smart dimension to give them a size
then i double click on the 2 dimensions sepearately to make them the same as each other
but i get a dialogue box with the dimensions greyed out and cant change them.
Now I finally understand. There's another workflow for what you're trying to do that I think will work better. After placing the two circles, Ctrl+select them and set an Equal relation. Then you only need to dimension one of them, and you can do that before or after making them Equal.
If you just want to do it with a dimension instead of a relation, that's also possible. Use the Smart Dimension tool to set the dimension for one of the circles. Then with Smart Dimension still active click on the second circle, type = in the text box, click on the dimension of the other circle, then hit Enter (or click on the green check mark) to set this dimension as equal to the first one.
yep thats ok but on the smart dimension for the rectangle the doubleclick on the numbers refuses to allow me to change the dims.
i can of course go into the sketch and change the dims but its a nuisance with doubleclick not working
thanks for your advice glen
Do these two circles already have an Equal relation between them.
If they do you can still dimension them both but one will be Blue editable, the other Grey non editable.
The Grey dimension will change automatically when the Blue one is double clicked.
i have figured where i was going wrong .i had closed the sketch then put the dims outside .
when i kept it open and put the dims inside then double clicked on the sketch then double clicked on the dims all is well.
just a couple of twitches on the mouse button in the right sequence did it .
silly newbie mistake ....duhh
