convert autocad drawing to 3d model

By Mark Lancaster, Synergis Engineering Design Solutions

Accept you ever contacted a vendor requesting a 3D model of their product and you lot only received a 2D drawing of it? I will even bet the drawing you received had limited amount of information on information technology as well. Then what steps did y'all accept to catechumen their 2D drawing over to 3D?

Granted there are a few workflows out there to accept 2D geometry and make a 3D model from it, but with the release of Inventor 2016, it but got easier. For example, let's say yous only have access to a second drawing file of a stainless steel barbed connector from McMASTER-CARR

First allow'south start out by creating a new function in Inventor 2016. For my configuration, no new sketch is created when I start making a role.

• Next, select Import located nether the 3D Model/Create ribbon section

• Navigate to and select (open) my 2d cartoon
  • At this bespeak the drawing you're importing should exist placed somewhere in the active Inventor project area.
• Select on of the work planes to place the drawing
• Select the point (origin or 0,0) where the drawing volition exist inserted.
  • This signal will match the (0,0) location on the drawing
• Accept the message about the file not being saved and/or well-nigh the associated underlay that's being created.

• The drawing should now appear on the work airplane you selected earlier

• At this indicate the cartoon may be inserted at the incorrect orientation and/or wrong calibration.
  • For the scaling aspect, I will encompass that shortly.
• To reorient (if needed), right mouse click on the cartoon in the browser and select Translate. From there I can use the rotate triad method and plow my drawing 90 degrees.

• Create a 2D sketch on the aforementioned work airplane that was used when importing the cartoon.

• Now we need to outset projecting the drawing geometry that will make upwards our sketch. Select the drop down under Project Geometry and pick Project DWG Geometry

• Since I planned on making a revolved extrusion of this part, I will but projection a certain corporeality of the 2D geometry. I'grand likewise projecting the ends of the connector equally construction lines in order to make up one's mind my axis of rotation.

• Next I volition stop up my sketch past creating the missing geometry that will form the revolved extrusion.

• Now permit's revolve it and save the part file.

• If I bank check the overall length of my revolved extrusion, you will observe the scale of the imported drawing is not at a 1 to i scale. In order to change the drawing scale I will need to open the 2D cartoon file directly in one of the AutoCAD platforms.

Although I'm using AutoCAD 2016, the drawing tin can exist modified in any version of AutoCAD every bit long as it'southward able to open it.

• I'll calibration the drawing based on the origin (0,0) point and the other thing I will practise is move the entire drawing so one of the connector ends is setting at the drawing origin betoken.

• Save the drawing and exit AutoCAD.
• Now when I return back to Inventor, a cherry lightning bolt is nowadays side by side to the (imported) drawing in the browser and the update icon is lit.

• Once I perform the update, the model is scaled down based on the updated cartoon and the finish of the part relocated and aligns with the origin plane/bespeak.

• Afterwards a couple of additional modeling steps my affront connector is now completed.

• At this point I could plough the visibility of the drawing off and/or suppress (or break) the link to the (imported) drawing.

In that location you lot accept it, a workflow that allows you to take 2D geometry and a 3D part from it. Until next time…
