![]() ![]() In the examples below I have changed the “Shaft Length” from 400mm to 250mm and the “Head Width” from 10mm to 18mm. GPODDER VARIABLE SPEED UPDATEThis will update the model allowing for quick changes. However this is changing in SOLIDWORKS 2013, allowing equations to be entered as the feature is applied.Īfter the global variables have been applied, they can be easily changed in the equations interface. When the dimensions are visible, double click it and edit the modify box in the same method as for a sketch dimension. This is done by right clicking on the Annotations folder in the Feature Manager Design Tree and selecting “Show Feature Dimensions”. To apply a global variable to a feature, the Feature Dimensions need to be shown. When in this mode, normal mathematical functions (+, -, /, *) can be applied as well as more complex functions (Cos, Tan, If, etc) Insert an equal sign and choose the appropriate global variable. To apply this to a sketch dimension, double click the dimension to bring up the Modify box. This ensures that the shaft is always 1.5 x “Head Width”. To ensure that the shaft remains thick enough for any sized Head Width, there has been an equation added to the shaft diameter. This menu has had a revamp since SOLIDWORKS 2012 version.įor this example I have modelled a simple screwdriver, with a global variables added to change the values for “Shaft Length” and “Head Width”. Global Variables can be found in the Equations interface under, Tools > Equations. ![]() This technique is useful when situations require speed modelling, whether this is during SOLIDWORKS exams or to quickly produce variations of a design for your CAD manager. Global variables are a useful tool for allowing quick changes to key dimensions within a model. ![]()
