Picture vectorization
You have 3 different way to create a Part from a raster image (picture):
The simplest way, if your picture is clean enough
Click the Cutting funcion you need 
			of the Startup 
					dialog (green icons) and select the picture (Gif, 
			Jpeg, Bmp, Png, Tif, Tga, Pcx).  If enabled you will see the 
				'AutoTrace elements' dialog if you select a raster file. Finally 
			you will se the cutting dialog 
			where you can create the right cutting path.
			
			If the result is not good, enable (if currently disabled) the 'AutoTrace 
				elements' dialog by the Setting link of the 
				Startup dialog and try to adjust as first the Thresold value. 
			Read also well the 
				'AutoTrace elements' help page to have more info to the right way 
			to have success.
			
			A second way, Import regions or polylines in the Cad 
					section
		
To try this way create a new Cad drawing, 
			then use the "File - Import... - Import Regions from many file types..."
			or the "File - Import... - Import Polylines from many file 
				types..." menu.
			If enabled you will see the 
				'AutoTrace elements' dialog if you select a raster file. Finally 
			you will se the Imported regions in your Cad drawing.
			
			Read also this pages 
				Importing regions in a new Cad drawing and 
				Importing polylines in a new Cad drawing.
			If the result is not good, enable (if currently disabled) the 'AutoTrace 
				elements' dialog by the Setting link of the 
				Startup dialog and try to adjust as first the Thresold value. 
			Read also well the 
				'AutoTrace elements' help page to have more info to the right way 
			to have success.
		
A Last chance, use a background image in the Cad section
			You can set it as a background image in a new Cad document, then trace it. See 
			also 
				And what can do devFoam Pro for the same problem?
			
			
		Here are the step to follow:
		
Set the background image
After you created a New Cad document (see 
				Cad feature of devFoam) use the 'Format - Background image -  
				Add background image' menu
			You will be prompted to select the image and if/how you want calibrate it. See 
			also 
				Inserting a background raster image in the drawing.
			We suggest to select Manual calibration. Calibration is the operation to size 
			the image to the wanted dimension. After pressing OK you will be prompted to 
			click two points whose distance is known, for example the Height of the 
			picture.
			Here is a picture of an example of raster background:
			
			
			You can also use the menu 'Format - Background image -  Set line 
				color of background image' to use a different color, so you 
			can see better the lines you'll go to trace:
			
Draw closed polylines around the contours
Now you must draw closed 
				Polylines around the contours. We suggest to use polylines so that 
			you haven't to fight against 
				dirty geometries.
			You can use lines and arcs, and remember to use the Close command of the 
			command bar to close the polylines as the last step.
			After you traced the polylines you can also select and refine them moving the 
			control points.
			Here is a picture of the previous example with the polylines:

Select the closed polylines and go to cut
Now you can select the polylines and use the menu 'Cut - simple foam cutting of selected Parts' to start the Simple cutting dialog:

And you can as usually preview the cutting job in 3D:
