Drafting, Tips

When you import 2D geometry from a DXF or DWG file, Solid Edge will translate the data and load it into a 2D Model view, but this is only the first step of the process.

DXF files especially will break the original data down to its most basic elements to ensure that any application can open it and is┬ásimilar to bringing a imported 3D model into a history based modeller – you have the geometry, but working with it is hard. This is because there are no relationships between elements and any edits will affect the element, but not the geometry around it – it is not parametric.

Building connectivity is easy in Solid Edge with the Relationship Assistant.

Relationship Assistant – Found in the Home Tab under the Relate section

When you open the relationship assistant, select the Option button from the smart step ribbon bar. The displayed dialog box has 2 tabs, one for applying the Geometric relationships and for applying dimensional constraints.

 

 

 

Dimensional Constraint Options

Geometric Relationship Options

In both cases, select the type of options you would like placed and click on the OK button. Typically, the geometric options shown here are all that is needed. Fence select the geometry you want to make parametric and click the Tick button. If you have chosen to place dimensions, you will also need to select a horizontal and vertical reference base line. The relationships are then applied to the geometry.

Making changes to the elements now will ensure that connected lines are also adjusted.
