The Control
This command enables to measure and modify elements and to get information about any type of element, at any time.
Four modes of use are available:
![]() | Manual measure |
![]() | Measure on solid |
![]() | Measure on profile |
![]() | PMI analysis |
These modes are contextual: if there is no solid in the part, the dynamic measure does not appear in the command. But if there is one or several solids, the dynamic measure is the default mode of the command.
The manual measure
The manual measure offers two types of information:
a measure between two elements
information about the characteristics of the element
Measure between two elements
It can be done in: wireframe geometry, solid corner, machining stock, toolpath.
Several measures are displayed on the screen and in the information window, according to the selection done in the dialog area:
The direct distance (D) between the two elements
The distances on the axis X, Y and Z
The positioning angles expressed in the current plane
Measure of 2D geometry taken from a DXF file: ![]() | On a solid, you can get values that measure on solid cannot find: here, the position of the hole center according to the yellow face, 76 mm in X axis. For this, click the center of hole and then the solid corner. ![]() |
Information about the characteristics of the element
For this, after clicking the element on the screen, click the button ‘Element Characteristics’ in the dialog area. The information obtained are different according to the type of element selected. For example, for the linear geometric elements (segment, line), GO2cam displays the positioning angle in the plane XY and the length of segments.
It is possible to display these values in cartesian mode or in polar mode: make the popup menu appear with a right-click in the background screen and then choose Polar measures.
The measure on solid
The dynamic measure has three purposes:
measure distances and angles on the solid faces
modify the measured values (in accordance with the solid topology)
give tolerances to the measured values
Measure distances and angles on the solid faces
This action is applied on the solids and on the machining stock. This enables to click faces and to accede to a great number of modes of measure.
Symbols can also be selected. So, you can measure a distance between stock or part and vice or clamps for example!
For the measure on solid mode, the list of options is now displayed in a combo box with a self-explanatory diagrams and the number of clicks required for the action. Find some examples below:
| ![]() |
The options can also be accessed by right-clicking on the background after selecting the control command. | ![]() |
Display: purple arrows are displayed to indicate the selected faces. When the stock is selected, the arrow appears in grey. Measurements can then be taken between the solid part and the stock to determine, for example, the amount of material to be removed. | ![]() |
Topological Information
This mode is not really a measurement but enables to obtain information about the solid faces. Move the cursor on a face and it will display its type (plane, cylinder), the orientation (vertical, horizontal, taper…) and sometimes a value (radius, angle,…). This command can be used both in the design environment and in the machining menus when selecting geometry or tools. The information provided can assist, for example, in selecting the appropriate tool. | ![]() | |
Table of topological information:
Type of face | Information displayed |
Plane | Vertical, Horizontal, Taper, Undercut |
Cylinder/ Face | Radius |
Holes | Radius + angle if conical |
Cone | Angle, maxi radius and mini radius |
Torus | Radii |
Bspline / Iso Surfaces | Mini curvature radius |
Use
When you select a measure mode and click the face(s), the value is displayed on the screen. If a ‘pencil’ symbol appears, click it to enter a Rapid Edit menu, where the value can be modified.
The measure between the two arms of the clevis gives the value of 40 mm. The measure mode used is ‘Distance Cavity’, with one click, but it could have been ‘distance between faces’. Clicking the dimension opens the RapidEdit box for modification. | Then enter 32 mm. The button on the right shows a single arrow. It means that the modification is applied in one direction, according to the face clicked. (or first face clicked in case of ‘measure between faces’). ![]() | By clicking the button, a double arrow is displayed and the modification is applied symmetrically. ![]() |
![]() | ![]() | ![]()
|
Features
Those options are contextual, they appear according to the mode of measure and the selected element:
One side/Both sides: as explained above, apply a modification in one direction or symmetrically.
Selection of similar faces: this option enables to repeat the actions from the current element to all the identical elements! If a hole or a groove is modified or assigned a tolerance in turning, this command can be used to apply the same change to all similar geometries.
Chained fillets: this option gives the possibility to modify the radius of a fillet and to all the tangent fillets.
Elements: while using the mode ‘Topological information’, some elements are directly recognized as their type not geometry, such as the Holes and the Keyseats in turning
![]() | ![]() | ![]() |
Tolerancing
With the same process, you can apply tolerances to some values. Let’s take the example of a 6g6:
If the tolerance g6 is entered, the average value is applied: 5.992.
If g6- is entered, the lower value is applied: 5.988.
If g6+ is entered, the upper value is applied: 5.996.
A tolerance interval may also be specified. For example, 6IT(-0.15, +0.05) applies the average value: 5.95.
The hole diameter is 30 mm. | Apply H7 tolerance. | The average value is applied to the geometry: D30.011 mm |

The measure on profile
This command enables to control the profiles and obtain some important information.
First create a profile with a bounding box or by defining the starting and ending elements.
Once the profile is created:
Some information are displayed on the screen, on the profile: profile number, Z altitude, values of radii.

Many information are displayed in the Information Window:
A simplified iso enables to obtain the calculation of toolpaths,
The main characteristics of the profile: number of elements, length, mini radius, maxi radius, etc.
Simplified Iso:

Main characteristics of the profile:

The access to the different modes for the measure on profile option is available through the combo box in the dialog area.The different modes available are:
![]() | Automatic | ![]() | Silhouette Pocket |
![]() | Bottom Face | ![]() | Lateral Face |
![]() | Silhouette | ![]() | Wireframe |
![]() | Profile |
PMI analysis
GO2cam is also able to read PMI from CAD files. In Control, the option PMI analysis can show the faces concerned for each dimensions selected. | ![]() | |
New function in the PMI to run the measure between two solid faces to modify the value. This only works for annotations of distances and diameters. | ||
Types of PMIs added in ‘Part Info’ The detail of number of PMIs by type is given:: Nb Dimensions (semantics) Editing dimension does work only with Dimensions (semantics) | ![]() | |
