Hello,
I will continue the series of articles, which started yesterday, by explaining the settings we can apply on the dimension line. Let’s delete the dimension we have created yesterday and create a new one by choosing the new dimension style we created (Architectural-1). Now, let’s enter dimension style settings from (Dimension Style…), which is on the right side of dimensioning toolbar and, although there will be Architectural-1 in the dialog box opened, let’s press Modify button.
Fig. 1 Let’s start by pressing Modify button
Dialog box, which is shown in Fig.2, will pop up. You can see tabs that separate the dimension settings into groups. In this article, we will pass on to Lines tab and learn the settings there.
Fig.2 Let’s go on by going to Lines tab
Now, I will go on by playing with all of the settings you can see here. I will put less word and many examples in order to ease you learning process.
Color
Fig.3 Color of dimension line
If you change this value, default of which is BYBLOCK, the chosen color will be applied to the dimension line. Due to the fact that, dimension line and the extensions are a whole, color you have chosen will affect all of them.
Dimension Line Weight (line thickness) and line type
Fig.4 It will suffer more.
Figure explains everything… However, if the attributes, like color and linetype, of elements that form up the dimension inherit from LAYER, it will be easier for you in the future regarding the possible changes you will make.
Extend beyond ticks
Fig.5 Extensions of dimansion line
This value, which I also explained in my previous article, can be at an amount of which extension lines extend beyond the dimension line, according to the architectural discipline. If you are using dimension arrows this option box will already be unavailable.
Baseline spacing
Fig. 6 spacing between two dimension lines
It you are making dimensioning by leaning on an extension line or taking one in the middle, then you have to set the distance between them equal to each other. By using this option, you can determine the spacing between two dimension line.
Supress dim line
Fig.7 Necessary of not?
I don’t know if this setting is necessary or not, but they have included it. Left side is dim line 1 and right side is 2. Now it’s time for extension lines. As the physical properties, like color and line type, of these elements are same as the previous one, I will go on with the next setting.
Suppress Ext. Line 1 or 2
Fig. 8 This setting may be useful
The more useless the previous one is, the more useful this one is. It may be necessary if we decide to make dimensioning of interior areas or if we want to use the own edges of the model as dimension line.
Extend beyond dim lines
Fig. 9 Extension property
No need to explain, as it is obvious.
Offset from origin
Fig.10 Offset from origin
There is one point at the end of each dimensioning extension line. Most of the inexperienced users think that these points are done by mistake. However, these points are the most important part of the dimension entity. Value of the dimension is the measurement between these two points. In case of automatic dimensioning, dimension style changes according to the angle that two points form up. Distance between these points and the extension line is called offset from origin.
Fixed length extension lines
This setting is ideal when you want all of the feet of extension lines to be on the same alignment. Click it and enter a value. Believe me, it is very useful.
Have a nice working.

The dimension sample in Fig 7. is not really useless, it is commonly use in running dimensions on drawings for machining components where several dimensions are originating from one datum or projection line. It is a simplified method of Parallel dimensioning. The dimensions are cumulative from the datum or origin. This dimensioning method is use where dimensioning tolerance is an issue.
