5.3.2 Distance
With the function Measure you can measure distances between edges, planes, axes, etc. and lengths, radii, etc. of edges and curves. These result from the selection of different objects and measurement filters.
command.
Distance
To determine the direct distance between two points you must first define the two points. If you have activated the Distance
measurement filter, the distance between these two points is now displayed. The first point defines the start point and the second the end point. If you want to move the start or end point afterwards, select the corresponding point in the list and change it as desired. In addition to points, this function is also supported directly for curves, edges, surfaces and volumes. The minimum and maximum distances (selectable via a dropdown menu in the displayed annotaion) between two objects are measured here(see figure "Distance").
Projected distance
- 1. In the Measure dialog, set "Object to Measure" to "Point". Use the measurement method "Free"
.
- 2. Click on both points you want to measure the distance to each other. The selected points should appear in your object list.
- 3. Select the lowest element in your object list, so that it is highlighted blue (a vector specifying the direction of your measurement has to directly follow the points you want to measure).(
see figure "Object list")
- 4. If you previously selected points, the last element in your object list will still be named "Select a point", as soon as you set "Vector" as object to measure, it will be renamed to "Select a vector"and 6 blue vectors that represent the main coordinate directions appear.
- 5. Now choose the vector corresponding to the direction in which you want to measure, this can be done by selecting one of the three blue Vectors or by specifying a custom vector using the Vector Dialog
.
Depending on the points and vector you selected, your result should now look similar to the picture on the right (see figure "Projected distance").
Should you now want to measure the distance between previously selected points in another direction, click on your previously specified vector in the object list and edit it using the Vector Dialog
. To enable selection of a new vector in the vector dialog, you have to deselect Fixed in the upper dropdown menu and set it to e.g. Inferred vector.
Length
To measure the lengths of edges and curves, you must first activate the Curve/Edge
filter. If you now select a single edge, its length will be displayed (see figure "Edge length"). This function is very useful to measure the length of lines and arcs.
Set Object to measure to Object Set to select multiple edges and/or curves. NX now shows you the sum of the length of the selected edges.
Radius and Diameter
To measure the radius or diameter of a hole or fillet, for example, or an arc or circle in general, select the Curve/Edge
measurement filter again. Then select the edge or curve to be measured (see figure "Radius & Diameter").
Complicated radii that have no immediate edges, such as an edge fillet on the base or top surface of a cylinder, cannot be measured directly. To measure the radius of such a surface, first select the Face
measurement filter and the corresponding surface to be measured. For fillets with a constant radius, the Min Radius of Curvature measurement returns the radius of the fillet (see figure "Radius from surface properties"). Alternatively, you can determine the radius, for example, by measuring the projected distance (see figure "Radius from projection").
Screen Distance
In addition to Measure there is also the Screen Distance
function. This function is used to measure distances between two points in the screen plane, as in a 2D drawing. Care should be taken as the program does not always select the edge that should be selected. As a result, the measurement result does not always reflect the required distance. Do not use this analysis function in 3D modeling.
