hand drawing to 3D model

hand drawing to 3D model

hand drawing to 3D model


I have drawing that was done by hand, and I scanned it into a pdf. there is no electronic version of the drawing, only a hard copy sheet.
I need to make a model from the drawing. drawing only has basic dimensions, no radius's on curved lines. Its a hand drawn image

Is there a way to import pdf into the drawing or model, and use these lines to build my model.
There is curvature and I need to have it in my model to copy from when I am building my model, other ways there is no other possible way for me to get the shape correct.

Path 1: import pdf into dwg (somehow), then use power drafting to create model.
path 2: import image in drafting or modeling background, use it to build my curves/lines and than remove the image and then use curves to build the model. With this method I will be approximating and trying to manually best fit a line to the image on background. A little time consuming and low tolerance results, but acceptable.

please share your ideas.

Try the Aide pdf-dwg trail software, I have had some decent results.

If not try Inkscape. See this video.


Hope this helps!


RE: hand drawing to 3D model

If a raster image was imported into a pdf file, don't expect great results from a pdf to dxf translator. Tools do exist to help convert raster images to dxf, but the results usually require a fair amount of hand clean-up.

If you are running NX 9 or newer, I'd suggest scanning your drawing to a raster image (jpeg, png, or tiff) and importing it into the modeling application (menu -> insert -> datum/point -> raster image...). Then you can sketch or create curves on top of the image, using it as a guide. You can do the same in NX 8.5 and below, but you will need a special license (studio visualize?) to import the image into modeling and I think the image must be in .tiff format.


RE: hand drawing to 3D model

If the part is simple enough to be imported and understood by the software, save yourself the time and build a fully parametric model from scratch.
If the part is a 3D complex shape, there is no software that will build a 3D model from a 2D hand drawing.
