Model Data

The current state of the model can be analysed using the Model data tab.

Model Status

The Model Status tool presents a summary of the model dimensions and the number of entities of each type occurring in the model. The Model Status tool can also be used to scale the model from one unit system to another.

Summary data

The model summary data identifies the minimum and maximum dimensions of the model along the three principles axes, and the minimum and maximum edge length in the model. The overall model diameter is also identified.

This information often provides useful clues to the state of the model and an indication of whether the Wizard repair operation is likely to succeed. If an IGES model has been imported, for instance, the Model Status tool should be used to compare the minimum edge length with the tolerance used to merge entities in the Wizard. If the tolerance is many times greater than the minimum edge length this may a sign that the data in the IGES file header is incorrect. The model should then be re-imported using the option "Calculate a good tolerance value", thereby ensuring that no parts will be collapsed during the repair process.

Model units

The model units link can be used to specify the model units, if they were previously unknown, or to scale the model from one unit system to another.

Choose the new model units from the list menu.

l              Choose Change units and scale model to change the model units and scale the model accordingly.

l              Choose Change units without scaling model to change the model units without physically scaling the model.

 

Model History

The Model History tool presents information relating to the original source of the model and a summary of the operations performed on the model to date.

For example if an IGES model has been imported into CADfix, the Model History tool will show the IGES Global Data and the Major Import Options used when the model was imported.

The actions performed on the model to date will also be stored as part of the model history:

Mass Properties

The Volume of a solid and surface area is calculated on a facetted representation of the model.  The Centre of Mass, global and local moments of inertia are also presented. The calculation works on the content of the Working set and therefore this must contain either faces or bodies or both. The calculation is an approximation based on the tolerance chosen:

When the working set only contains faces just the surface area is calculated.  If the working set contains bodies the user may elect to just calculate surface area for each face of each body by selecting each face.
