1. Click the arrow under the Dimension tool and select Dimension.

2. If you are creating a dimension in 3D, click a face to create an annotation plane on which to place the dimension.

   If you need to change the annotation plane, right-click and click Select New Annotation Plane from the context menu and select a new annotation plane.

3. Click an edge or face that belongs to the chamfer.

4. Mouse over your design to preview the possible dimensions.

5. Click to create the dimension.

DimensionsValues or expressions you enter for precise control during the creation or modification of a design. You can dimension every element, from lines in sketches to faces of solids. See Ordinate dimensions, Progressive dimensions, Ruler dimension. for planar and cylindrical chamfers.

 

You can flip the orientation of chamfer dimensions by setting the Flip ChamferSloping corner between two edges created using the Pull tool; angle with equal setback; bevel. Dimension property to True.

Flipped chamfer dimensions

 

Annotation options in the General page of Detailing option in SpaceClaim Options offers choices for how chamfer dimensions are displayed.

 

• Default chamfer dimension style:
  • Linear: Displays the dimension with extensions lines as in the images above.
  • NormalThe vector that is perpendicular to a flat plane at the selected point. In the case of a non-flat plane, the vector that is perpendicular to the plane tangent to the surface at the selected point. to chamfer: Displays the dimension with a leader pointed normal to the chamfer as shown in the image below.

    

• Default chamfer dimension text format:
  • <length> X 45: Text is displayed as in the images above.
  • C<length>: Text is shown as in the image below.

    

1. Click the arrow under Dimension in the Annotation group on the Detailing tab and select Ordinate Dimensions.

2. If you are creating a dimension in 3D, click a face to create the plane on which to place the dimension.

   Mouse over the faces of your design to preview the eligible annotation planes. (In Sketch and Section mode, the sketch grid defines the annotation plane.) If multiple objects occur at your cursor location, use the scroll wheel or arrow keys to highlight each one.

   To create an annotation plane for a cylindrical face, select the cylinder's axis.

   If you need to change the annotation plane, right-click and click Select New Annotation Plane from the context menu. Then right-click the new place and click Set As Annotation Plane.

3. Click a line, edge, or Center Line to set the baseline dimension.

   You can use an existing extension line as a dimensioning reference. An extension line is the line that connects the point to the dimension text. If you select an extension line, the baseline dimension for the extension line's dimension is used.

4. Mouse over the face to see all the possible dimensions.

   In cases with many ordinate dimensions, the preview may be slow. Start SpaceClaim using the following command line option to limit the number of dimensions that are shown in the preview. The example specifies '10' but you can set it to any number you wish.

   MaxOrdDims=10

   The plate shown below has 400 holes but only 10 are shown in the preview.

   

5. Click a point to place the dimension line.

   If you select a face, all of the possible ordinate dimensions will be created.

   You can click multiple points to use the same baseline for those dimensions.

   The baseline dimension (0) is displayed or hidden based on which detailing standard is selected in the Detailing options.

   Automatic jog points are included if ordinate dimensions are too closely spaced. This helps make them easier to read.

Using an angled baseline

First, establish a simple, oriented dimension. Then use one of the witness lines to set the baseline and orientation of the ordinate dimensions.

In the example above, the leftmost witness line of the existing circle-to-circle dimension was selected to define the baseline.

1. Start with a radius dimension

2. Optional - Set the Foreshortened radial dimension center size in SpaceClaim Options

3. Right click and select Foreshortened

   

4. Move the endpoint and jog points as needed.

5. Dimensioning to the center produces a foreshortened length dimension.

   

1. Click the arrow under the Dimension tool and select Dimension.

2. Click the Select bodies tool guide on the right side of the Design windowArea in the user interface that displays your model or assembly. Also known as Workspace..

3. Select the solid body or bodies you want to dimension:

   • If you select a single body, then the maximum horizontal or vertical dimension is created, as shown below.

     

   • If you select more than one body, then the dimension is created for both solids and is anchored on the side closest to where you click on the solid. You must click on the Select bodies tool guide before you select each solid, so you click the tool guide and select the first part, then click the tool guide again and select the second part.

     In both of the examples below, the upper part was selected near its top. The lower part was selected near its top in the example on the left and near its bottom in the example on the right. The mouse arrows indicate where the lower part was selected. You will see a preview of the dimension when you click the tool guide and hover over the second part.

     

   • If you create the dimension in a section view of a drawing sheet, then the dimension is created on the extents of the body that is visible in the section plane, as shown below.

     

1. Select the dimension annotation to move, size, or rotate it.

   To move the dimension note, mouse over the edge of the box with the Select tool until the cursor changes to , then drag the note.

   To size the box that contains the dimension note, drag the handles of the note box (the white circles).

2. Select the text of the note to reformat it.

3. (Optional) Right-click the dimension and select text formatting options from the mini-toolbar.

   Click to select a tolerance format, then edit the text of the tolerance.

   • See the Limits and Fits Tolerances section below for a description of using Limits and Fits.

   Click to insert a field. You can select a field type and format from the Insert Field window.

   Select from the drop-down to insert a symbol.

4. Click an arrowhead to cycle through alternative leader styles.

   You can also right-click an arrowhead and select Arrow Style to select a style for that arrowhead, or select the arrowhead, then select the style for the head in the Properties panelArea of the user interface that displays editable details about the selected object(s). This panel is initially displayed on the lower left side of the screen, but can be moved..

5. Click the note leaders to modify them.

   You can right-click a leader and select Add Jog PointSingle location in the sketch grid. 2-D object that has no height, width, or length. The origin, an axis, and a vertex are examples of points. Use the Point tool to sketch a point on the sketch grid. Points are useful as a dimensional reference, for splitting, and for creating a point on a line or curve through which you want to draw a three-point circle. to add a new point.

6. To change the distance between a dimension extension line and its reference point on the object, click on the extension line, then hover over the end closest to the object. Drag the red dot to change its distance from the object.

   If you cant' see the extension line, hover over the end of the dimension leader, where the line would be. You will see two red dots that you can drag:

   

7. Modify the dimension note properties in the Properties panel. Modify the:

   • Arrow Length and Width properties to set the length and width of the arrowheads

   • Measurement property to change the measurement type. For example, you may want to display the radius of a hole instead of the diameter.

   • Precision property to change the number of decimal places.

   • Upper Limit, Lower Limit, and Type of tolerance property to change the format of the dimension and enter upper and lower tolerance values.

8. To fit a dimension within the text box
   • RMB Click on the note and open the Autofit drop-down menu.
   • Choose one of the following options:
     • Do not autofit: The text box adjusts to the size of the text and grows as you type. There is no blank space around the note and making the text larger or smaller adjusts the box accordingly.
     • Resize text height on overflow: The text always fits the width of the box. If you make the box wider, text from the second line will move up to the first line.
     • Shrink text on overflow: The text adjusts uniformly (width and height) and scales to fit in the text box.
     • Shrink text horizontally on overflow: The width of the text changes but the height remains the same.

Limits and Fits tolerances are supported for Metric units using the ISOInternational Organization for Standardization standards for architectural and engineering drawing, including guidelines for dimensioning and tolerancing. You can customize the style of your annotations to conform to ISO standards. See ASME, JISJapanese Standards Association standards for technical drawings. You can customize the style of your annotations to conform to JIS standards. JIS defaults are the same as ISO, except that JIS uses third-angle views while ISO uses first-angle views. See ASME, ISO.. 286-1 and ISO 286-2 standards. Refer to these standrads for a complete description of Limits and Fits tolerances.

You can apply Limits and Fits to metric dimensions for Holes, Shafts, and opposing planar faces (i.e. face normals point toward each other).

 

 

 

Limits and Fits tolerances are specified with a letter and a number that refer to a table in the standard.

To apply a Limits and Fits tolerance

1. Select one of the dimensions listed above
2. In the Properties panel, change the Tolerance Type to Limits and Fits, or click in the mini toolbar
3. Based on the dimension size, the following tolerance properties are set to default values:
   • Upper Limit - The largest allowable value for the dimension
   • Lower Limit - The smallest allowable value for the dimension
   • System of Fits - Sets the fixed datum used to calculate the tolerances. This can be either Hole Basis (shaft is assembled into the hole) or Shaft Basis (hole is assembled onto the shaft).
   • Hole Fundamental Deviation - Fundamental Deviation establishes the location of the tolerance zone with respect to the Basic Size. When System of Fits is set to Hole Basis, this will be "H". When System of Fits is set to Shaft Basis, this can be any of the allowed letter designations (A thru ZC)
   • Hole IT - "IT" refers to International Tolerance Grade. It is a group of tolerances which vary depending on the Basic Size of the dimension, but which provide the same relative accuracy within a given grade .Any of the allowed numeric designations (IT01 thru IT18)
   • Shaft Fundamental Deviation - Fundamental Deviation establishes the location of the tolerance zone with respect to the Basic Size. When System of Fits is set to Hole Basis, this will be any of the allowed letter designations (a thru zc). When System of Fits is set to Shaft Basis, this will be "h".
   • Shaft IT - Any of the allowed numeric designations (IT01 thru IT18)
   • Method of Designating - The display format for the tolerance
4. Change any of the properties as appropriate

In the Limits and Fits section of SpaceClaim Options > Detailing, you can set defaults for the properties.

Limits and Fits symbols combine the IT Grade Number and the Fundamental Deviation letter. "IT" is dropped from the Grade Number so only the number is shown. The tolerance size is thus defined by the Basic Size of the part followed by a symbol containing a letter and a number. A Fit is indicated by the Basic Dimension common to both components, followed by a symbol corresponding to both components with the Internal part symbol preceding the External part symbol.

The table below shows examples.

 

Internal (hole) component
External (shaft) component
Fit between a hole and shaft with a basic size of 40

 

Set the Method of Designating property to change the symbol's display format. The table below illustrates the choices.

40H8
40H8 (40.039/40)
40.039/40 (40H8)
40.039/40
40H8/h7

When you change the size of a dimension that has Limits and Fits tolerances, the Upper and Lower Limits will change according to the limits and Fits tolerance tables.

If you modify the IT number, the tolerance symbol updates accordingly.

The dimension color is changed to Red if it has Limits and Fits tolerance and some of the input parameters are invalid. An example is shown below.

The tolerance has a Fit for H01/n01
The Fit was changed to H01/a01, which is invalid

 

1. Create two layers, one for notes, and one for the annotation planes.

2. Place the note on one layer and the annotation plane on another layer.

3. Turn off the visibility of the layer that contains the annotation plane.

   • Align Middles - Horizontally align the middle of each dimension.
   • Align Bottom Lines - Align the bottom of the last line of text in each dimension.
   • Make Same width - Make each dimension the same width based on the first note selected. Some text may be scaled accordingly.
   • Make Same Height - Make each dimension the same height based on the first note selected. Some text may be scaled accordingly.
   • Make Same Size - Make each dimension the same size (height and width) based on the first note selected. Some text may be scaled accordingly.
   • Distribute Horizontally - The space between each dimension is distributed evenly horizontally.
   • Distribute Vertically -The space between each dimension is distributed evenly vertically.
   • Remove Horizontal Spacing - The even horizontal spacing is removed and any significant overlap is equalized.
   • Remove Vertical Spacing - The even vertical spacing is removed and any significant overlap is equalized.

Any notes rotated differently are not affected by the above commands.
