Dimensioning is a key practice in drafting various working drawings. Land F/X provides a system for dimensioning that is quick and painless – if you know how to use it. We’ll show you all the necessary steps for setting up Dimension Styles (DimStyles) and saving them into Land F/X. We’ll also provide some general practice tips and go over some common troubleshooting items.

0:00 – 2:37: Intro/TOC
2:38 – 12:57: Introduction to Dimensions
Dimensions and AutoCAD (2:38)
AutoCAD provides a robust dimensioning system.
Default dimensions are not scaled automatically.
Dimensions are placed on the active layer.
The Dimension Style (DimStyle) Manager (3:20)
Custom changes are made in the DimStyle Manager.
Customize items such as arrowheads, units, text styles, linetypes, spacing, and tolerances.
Set Current to use the DimStyle.
DimStyle settings and scale (4:17)
Scale is managed by you.
Multiple scales means maintaining multiple styles.
To transfer DimStyle settings, these dimensions must be defined in a template file, or you can use the Import/Export Express tool.
With all there DimStyles to manage, and no automation, it’s easy to become disorganized and lose consistency with your dimensions. (5:33)
Dimensions and Land F/X (5:50)
We’ve simplified AutoCAD’s dimensioning system for ease of use. By default, dimensions are set to go.
Out of the box, you can open a detail drawing and place dimensions without any extra setup. Text Style, arrow style, linetypes, scale, plot style configuration, etc. are all automated.
When you use a Land F/X dimension tool, a Land S/X DimStyle is created automatically and set as current. (6:59)
Dimensions and layers in Land F/X (7:50)
Land F/X dimensions are automatically placed on appropriate layers.
- L-DETL-ANNO-DIMS = detail dimensions
- L-SITE-ANNO-DIMS = site dimensions
The Land F/X DimStyle (8:29)
The Land F/X DimStyle is based on the style that’s saved in Preferences and adheres to the plot scale chosen.
Example: LANDFX-SD20 = Land F/X Site Dimension @ 20 scale
Customizing dimensions in Land F/X (8:55)
- Customization still occurs in the DimStyle Manager.
- One-time setup.
- Custom style saved into a Preference Set.
- Unique DimStyle for details and site.
- Scale changes are automated.

Customizing DimStyles with Land F/X (11:30)
Basic workflow and rules:
- Start with a new drawing!
- Set up the drawing with units and a plot scale.
- Place a Land F/X dimension so a Land F/X DimStyle will populate the DimStyle Manager.
- Modify that Land F/X DimStyle to match your standards.
- In Preferences, save the DimStyle.
- Test the DimStyle by using that Preference Set in a new drawing and placing a dimension.
12:58 – 34:59: Creating a Custom Dimension Style
Opening a new drawing and setting the units (13:20)
Setting the plot scale using our Scale tool (13:37)
Placing a dimension (14:05)
Opening the DimStyle Manager and modifying the active Land F/X DimStyle (15:05)
Customization options (15:30)
Settings in the Modify Dimension Style dialog box:
Settings for dimension lines (Lines tab) (16:00)
We recommend keeping the color as ByLayer.
Symbols and Arrows settings (17:50)
Text settings (19:23)
We recommend using the DIMENSION TEXT Text Style and managing it through your Preferences.
Settings for fitting dimensions (Fit tab) (21:11)
Note that Land F/X sets the scale for dimension features automatically. Don’t change this number if you’re using a Land F/X DimStyle.
Primary units settings (21:35)
Tolerances settings (22:25)
We recommend leaving these settings as is.
Saving a custom DimStyle into Land F/X (23:01)
Unit settings for detail and site DimStyles saved into Land F/X (24:00)
DimStyle reference sheet (25:00)
When you save a DimStyle, the system will automatically create an 8 1/2-by-11-inch sheet showing that style applied to all our dimension tools and the applicable System Variable settings. You can use this sheet as a reference.
Units settings (26:00)
Testing the DimStyle in a new drawing (26:40)
DimStyle layers (28:34)
Question: Is it possible to have a DimStyle with a different arrowhead to note radius, as AutoCAD r10 allowed us to do? (29:10)
Answer: You can do this in your Properties after the fact.
Question: Can we have one style for details and one for plan dimensions – for example, using Architectural for one and Decimal for the other? (30:45)
Answer: Absolutely! You can change settings such as the Primary Units and Precision and then only save the modified DimStyle into either the details or the site DimStyle.
Question: Sometimes when I dimension lines, the correct length isn’t shown. Why is this happening? (33:55)
Answer: This issue can result from an incorrect precision setting or an incorrect drawing setup.
35:00 – 52:17: Dimensioning Tools
Basic dimensioning tips and practices (from Landscape Architecture Graphic Standards) (35:05)
- Be consistent with the placement of dimension lines.
- Extension lines are preferable to inside lines.
- Dimensions should never be placed in shaded or hatched areas.
- Dimension lines should be concentrated in an area when possible rather than spread out randomly across a plan.
- Never place dimensions lines within a structure.
- Use an appropriate lineweight hierarchy.
- Dimension lines should never cross. When unavoidable, use a break line on the less-important line.
- Dimensions should lie near the measured item.
- Parallel dimension lines should be spaced apart equally.
- Decimals and feet/inch ticks need to be read easily.

52:18 – end: Common Troubleshooting Items
Troubleshooting issue #1: You’ve saved your custom settings into your Preference Set. Now you use this Preference Set in a drawing and the dimensions don’t look any different from before. (51:28)
Solution: It’s likely that a predefined DimStyle still exists in the drawing and will need to be removed/purged out before the saved style can populate the DimStyle Manager.
Troubleshooting issue #2: There are multiple DimStyles placed in your drawing, and you want them to reflect the current or custom style. (56:03)
Solution: Use the AutoCAD Match Properties (MATCHPROP) command or the Dimension Update tool on the undesired DimStyles.
Troubleshooting issue #3: The scale is wrong, or measurements are incorrect. (57:46)
1. Check and correct the scale and units.
2. Check -DWGUNITS settings.
3. (for scale issue only) Remove DimStyle and place a new dimension. Then use MATCHPROP to fix placed dimensions.
Question: Is it possible to dimension in Paper Space? (1:01:45)
Answer: Yes, but with caution. We don’t recommend it because certain dimensioning tools don’t work well in Paper Space, and it’s easy to make mistakes. For example, it’s difficult to select arcs and circles. Plus if you label in Paper Space, it’s likely that your dimensions will lose their associations with their objects.
Question: How do you account for multiple scales? Does the DimScale change automatically?
Answer: We suggest using Work Areas wherever you can. Work Areas work great for setting different scales in a single drawing. Your Dimension Styles will adhere to the scale set in the Work Area.
