Steps to Change Units in AutoCAD 2015
Changing the units in AutoCAD can be vital for ensuring that your drawings are accurate and suitable for their intended use. Here are step-by-step instructions to modify the units in AutoCAD 2015:
Accessing the Units Setting
1. Launch AutoCAD on your computer.
2. In the command prompt, type UNITS and press ENTER on your keyboard. A dialog box titled “Drawing Units” will appear.
Selecting the Unit Type
3. In the “Drawing Units” dialog box, look for the Length Type dropdown menu.
4. Choose the appropriate type of units you wish to use for your project (e.g., Decimal, Architectural, Engineering).
5. Next, navigate to the Insertion scale section to determine the scale at which your objects will be inserted. From the dropdown, select the unit corresponding to your project’s needs—metric or imperial.
Finalizing and Applying Changes
6. Once you’ve made your selections, click OK to apply the changes. This will update the units for the current drawing, and all subsequent work will reflect these unit settings.
Checking Current Units
7. To verify the current unit settings, once again type UNITS in the command line. The “Drawing Units” dialog will open, allowing you to see the current configurations.
Transforming Units: From Inches to Millimeters or Vice Versa
When working on projects that require a switch in measurements—for example, from inches to millimeters—follow these steps:
Converting Inches to Millimeters
1. Open your drawing in AutoCAD 2015 and access the Dimension menu.
2. Select Style from the menu options.
3. In the Dimension Style Manager, click on New to create a new dimension style.
4. Name the new style and choose an existing style to base it on.
5. Navigate to the Primary Units tab and enter “mm” in the Suffix box. Set the Scale Factor to 25.4, as there are 25.4 millimeters in an inch.
6. Save the style and apply it to your dimensions as needed.
Converting Millimeters to Inches
1. Repeat the steps above to access the Dimension Style Manager.
2. Click New, and name your dimension style.
3. In the Primary Units tab, enter “in” in the Suffix box. Set the Scale Factor to 0.03937, which converts millimeters to inches.
4. Save and apply this new style to your dimensions.
Frequently Asked Questions
What is the default unit in AutoCAD?
The default unit in AutoCAD is typically set to inches, meaning any measurement entered without a specific unit will be interpreted as inches unless the unit settings are changed.
How do I set drawing limits in AutoCAD?
To set drawing limits, type LIMITS into the command line. Specify the coordinates for the lower-left corner followed by the upper-right corner of the desired limit area. This helps create a defined working space within the drawing.
Can I switch between different unit systems in AutoCAD easily?
Yes, you can switch between different unit systems in AutoCAD by using the UNITS command whenever needed. It’s important to reset your drawing settings according to your project’s requirements to avoid discrepancies in measurements.
