dimensioning

Anonymous — Thu, 01 Feb 2018 03:08:20 GMT

I am having an issue adding dimensions to my drawing. Anytime I add a dimension to a line, the right dimension is written but it doesn't change the size. When I use DIST to check my dimension, I'll see it hasn't changed.

Can you post some screenshots, a screencast, or the drawing? it could be any one of a number of different things, such as DIMASSOCIATE not being set to 2, that can cause what you are describing.

@Anonymous hello, it could be controlled by your dimstyle > text height. or try to change your dimscale and see if helps. thanks

I've attached a screenshot. The dimension is 14.9645, when I try to change it to 50', the text will show 50' but the actual dimension is 14.9645 (I've confirmed this with measuring the distance. I don't know why I can't change the dimensions. Thanks for helping me look into this.

Hello,

Thanks for helping out, I tried that and I'm still having the same problem. My dimension scale factor is set at 1. I've attached a rectangle with a dimension on it to give you a better idea of my issue. I set the height to 20' but when I measure the distance on autoCAD it shows it's 2 ft. I can't adjust/change my dimensions.

You haven't just typed 50 in text override have you?

After adding the dimension arrow on my drawing, I double clicked the arrow and changed the value. I just checked and text override also shows 50. Am I adding the dimensions wrongly. In the older version of AutoCAD, I would just add the dimensions arrow and change the value. I am creating a floor plan for work and I've been trying to figure this out for a bit now. Thanks for your help.

I'm not familiar with Mac, and how it differs from Windows AutoCAD. It sounds to me like you are expecting the override of the dimension text to change your drawing?

The dimension text doesn't change the lines actually length no matter what you change it too. If you want the line to be 50' then you need to change the actual line to be 50'. Changing the dimension text has no effect on it.

I think you are thinking it works backwards. You are saying that you want to change the dimension text and have that line change to that length. How it works is if you change the length of a line the dimension text will change to match the new length of the line as long as the dimension was snapped to the endpoints of the line in question.

You should just draw your floor plan to a 1:1 scale making all the lines their true size. Then your dimensions will be what they should be.

Revit's temporary dimensions work like you are suggesting, but autocads do not.

That was exactly what I was trying to do. After making a drawing, how do I change/adjust the length/width of the line? Since changing the value after adding a dimension line (from the dimensions command) only changes the text. Thanks.

This is what I was doing

"The dimension text doesn't change the lines actually length no matter what you change it too. If you want the line to be 50' then you need to change the actual line to be 50'. Changing the dimension text has no effect on it.

How do I change the dimensions after making a drawing? I thought I would use the dimensions command to add an arrow then change the value on the arrow. Looks like I was thinking of it the wrong way. Thanks

if DIMASSOC is set to 2, if you use the lengthen command, you can change the length of a line and the dimension tied to that line should automatically update. if you have a box, it isnt quite so easy, as the box is closed, so the linework cant be adjusted so easily. Traditionally, I try to get my design as close to final as possible before adding dimensions, that way it is unlikely I'll have to change them a significant amount.

To make a line longer, click on the line then hoover over the blue grip on the end of the line you want to change. After a second a box pops up and you can pick lengthen. You can use tab to flip between entering a number for a new total length of the line or you can just add a distance to the the line.

you must lengthen the line, or in your example the rectangle with the stretch command.

What you are describing in your first post are CONSTRAINTS: could that be it?

I didn't know how to lengthen/adjust the size of lines in my drawing. But thanks to everyone on this forum, I know how to do it now using the lengthen or stretch command. Thanks for replying to my post.
