Making Profiles From CAD DWG/DXF Files

Making Profiles From CAD DWG/DXF Files
Beware of taking sketch information from any CAD drawings because the information is only as good as the original drawing.

A sketch may be under-dimensioned like the one we are going to work on. Or drafters may simply change the dimensions on the drawing rather than making actual changes to the lines when being rushed to get a project completed and out the door. I have done this myself. Simply explode the dimension and change the text. Management may not have the same commitment to drawing accuracy as the drafter would like and force last minute corrections to a drawing that override the inherent drawing information.

Most 2D CAD systems do not have constraints to do such things as force curves into tangency, the accuracy of curve transitions is left to the skill and experience of the drafter. With the bulk of production drafting commonly being done by employees in an entry level positions, the experience of the drafter may be minimal.

Additionally, consistency between views done with 2D drafting tools is left to the skill of the drafter. It can be common to encounter drawings that have discrepancies between view orientations, or even reflect different phases of a designs evolution.

So, take information from a 2D CAD drawing with care, because it can be faster and better to simply draw an Alibre sketch from scratch using the dimensional information provided by the drawing.

That said, let's create an Alibre Catalog Feature from a .dwg or .dxf file.
