Parametric models are easy to edit. A parametric feature is defined by its underlying sketch and the values entered when it is created. You can edit the sketch or the feature.
In the following image, the bracket on the far end of the shaft was created as a mirror of the other bracket. The mirrored bracket is parametric and therefore reflects changes made to the parent extrusion.
It is easy to edit a feature. You can select the sketch or the feature in the browser or the graphics window and right-click to display the editing options. You can edit the parameters of the sketch or the feature. As you make changes, both the original parameters and the changes are stored to assist in recovery if the model cannot update correctly.
You can edit a part after you have placed it in an assembly, either by opening the part file separately or by activating the part from the assembly. To edit a part in the context of an assembly, double-click the part in the assembly browser to activate it. When you are finished editing the part, double-click the assembly (the top level in the browser) to reactivate the part.
In the browser, an End of Part symbol is automatically positioned at the bottom of the model tree. You can drag the symbol up the model tree to "roll back" the model. This temporarily removes the features below the End of Part symbol from the model, providing easier access, and faster updating as you change the features above the symbol. To update the model, drag the symbol back to the bottom.
In Autodesk Inventor, you can use some commands while others are active. For example, you can use 3D Rotate while you are applying assembly constraints, or use Zoom while placing a symbol in a drawing. 3D Rotate, Zoom and other such commands are called transparent.
Most transparent commands can be selected from the ribbons when other commands are active. In addition, the following shortcut keys activate the viewing commands when other commands are active:
You can pre-select objects before starting any of the measure commands. If the selection set is compatible with the specified measure command, the results display. If the selection set is not compatible with the requested measure command, the selection set is cleared. For example, if three part edges are selected before you choose to measure distance, the selection set is cleared. If one object is selected and it is compatible with the requested measure command, the selection is retained.
On the Tools tab, Measure panel, use the Measure commands to measure distance, angle, loop, or area. Results are displayed in the measurement box.
On the Tools tab, Measure panel, select Measure Distance, Measure Angle, Measure Loops, or Measure Area.
Or, right-click in the graphics window and select Measure, and then select the option.
From the measure box, click the arrow to list options.
Clears the measurement from the Measurement box so that you can make another measurement.
Measures length of a line, length of an arc, distance between points, radius and diameter of a circle, distance between two components in an assembly (minimum distance), distance between two faces, or position of elements relative to the active coordinate system.
Click the arrow on the left to change selection priority to Component, Part, or Edges and Faces.
Measure UCS drop-down list
The drop-down list is available only if your active document contains a UCS. Origin option is listed first in the drop-down list followed with list of UCSes in your active document.
Shows measured distance from the origin of the part, or center point of the selected coordinate system.
Measures the angle between two lines, edges, or points.
Measures the length of closed loops defined by face boundaries, or other geometry.
Measures the area of contiguous, enclosed regions.
Add to Accumulate
Adds the measurement in the Measurement box to accumulate a total measurement.
Clears all measurements from the accumulate, resetting the sum to zero.
Displays the sum of all measurements you have added to the accumulate.
Precision/ All Decimals
Displays eight formatting values and the option to display all decimals.
