Why are my dimensions wrong in AutoCAD?
The units may have been changed from when the drawing was originally created. Check objects for Elevation or Start Z / End Z values (via Properties palette). Dimensioning from 2D to 3D space can throw off values. Reset AutoCAD to defaults (see How to reset AutoCAD to defaults).
What is scale factor in AutoCAD?
Scale Factor. Multiplies the dimensions of the selected objects by the specified scale. A scale factor greater than 1 enlarges the objects. A scale factor between 0 and 1 shrinks the objects. You can also drag the cursor to make the object larger or smaller.
What are the six kinds of dimension tools in AutoCAD?
The basic types of dimensioning are linear, radial, angular, ordinate, and arc length. Use the DIM command to create dimensions automatically according to the object type that you want to dimension.
How do I change AutoCAD from inches to CM?
Enter the scale factor. To convert from inches to centimeters enter 2.54 (there are 2.54 centimeters per inch). Or, to convert from centimeters to inches enter 0.3937 (the inverse of 2.54 centimeters per inch).
How do I reduce the size of a DXF file?
Solution: Depending on the content of the source DWG, the DXF can be several magnitudes larger in size. File size can be reduced if unused blocks and objects are removed from the DWG (see How to reduce the size of a DWG file in AutoCAD).
Do DXF files have dimensions?
If you export a drawing as a dxf, the dimensions you added won’t be included.
What is a DXF file used for?
A DXF (drawing interchange format) file is either a binary or an ASCII representation of a drawing file. It is often used to share drawing data between other CAD programs.
How do I change dimension text size in AutoCAD?
In the Dimension Style Manager, select the style you want to change. Click Modify. In the Modify Dimension Style dialog box, Text tab, under Text Appearance, select a text style. If the current text style does not have a fixed height, enter the height of dimension text in the Text Height box.
How do you scale an object?
Hold the Shift ⇧ key while resizing to scale the object only horizontally or vertically. Hold both the Shift ⇧ and Option ⌥ keys while resizing to scale the object proportionally from the center of its bounding box. Tip: Use the S keyboard shortcut to quickly select the Scale tool.
How do you scale up drawings?
Grid your reference and enlarge or decrease the ratio to draw a grid on your paper. Copy each box in proportion. Measure two points with scale dividers, the reverse end will mark those same points on a different scale. Enlarge a photocopy to size, shade the reverse side, flip it over and trace the outline.
What is the scale factor for 1 20?
1″ = 20′ Multiply the feet by 12. 20 x 12 = Scale Factor 240.
How do I change scale 1 to 100 in AutoCAD?
For scale of 1:100 use the SCALE command to scale the rectangle 100 times. Put this rectangle around what you want to plot then plot using Window and select the corners of the rectangle. Use scale to fit for the scaling and print it out.
What are 3 important properties for any drawing object?
Object properties control the appearance and behavior of objects, and are used to organize a drawing. Every object has general properties including its layer, color, linetype, linetype scale, lineweight, transparency, and plot style. In addition, objects have properties that are specific to their type.
What is the dimensioning?
Dimensioning is the process of measuring either the area or the volume that an object occupies.
Is AutoCAD in inches or feet?
Architects and Structural engineers draw in inches (1 unit in modelspace = 1 inch) while by default in Civil 3D, 1 modelspace unit is 1 foot/meter depends on your units setting. Civil3D import the objects in foot/meters, it is the dimension style that’s showing it in inches.
