Help with Rounding Down Dimensions

[Mase123y]

Ive been reading through the forum looking for how to round down dimensions. I see some topics with writing LISP codes to do it but I have Autocad LT and those cant use LISP codes right? Ive also been looking into the Round off variable in the Primary units for the dimension style but its a little confusing. What I want to do is just round down my dimension at the given precision.

 

Lets say I have my precision set to .000 (even though I may have dimensions with .00) I want my dimension of 2.875500 to round down to 2.875 and not up to 2.876 then I also have a dimension of 2.90952929 and I want that to round down to 2.909 and I can not find a way of getting both of these to round down with the same setting on the same dimension style. Basically I just want to truncate my dimensions.

You are right. AutoCAD LT cannot make use of lisp.

The only way I can think of off the top of my head to make this possible with LT would be to use a dynamic block with a field consisting of a DIESEL expression that truncates you value.

 

Just tried to test this out and you cannot insert a filed into a DIESEL expression, there may be a work around but I am unaware of it if there is.

Ok so the only way to do it then is individually in the properties screen for each dimension and change the Dim Roundoff I guess.

:unsure:Well, without knowing precisely what you are doing, it's hard for me to know what to really shoot for. I've never had a reason or known of a reason to need this. However, I can find at least one value that seems to work in these two specific cases. I'll leave it to you to figure out why it worked and if it will really work for you in general. DIMRND = 0.00077500

This may not be what you want but it can be done this way

 

You can change 1 dimension or 21 once the pop-up window is called up

after you change the 1st dimension just click on the next one to change it

when you are done press enter.

 

You can enter any dimension you want such as 23.75 - 23'-3/4" - 22-7/16" etc.

i tried using the DIMRND=0.00077500 on the command line in LT 2000 and got the following message "press F1 for help"

 

Just for kicks -- will what i posted in post #6 work in 2013?

Can you change DIMRND (Dim roundoff) in the Properties of a selected Dimension?

Well, of course it will "work", it just voids the actual dimension entirely. I use this technique myself when there is a break in the part and the actual dimension is incorrect anyway; or when I want to use the dimension form for something other than an actual dimension; or if I want to sabotage someone else's drawing so that they get in trouble for causing something to be fabricated to the wrong dimensions. The latter works especially well when they are editing the drawing via Stretch.
