ArtCAM Tutorial J. C. Lee 2007

Create Model from ImageArtCAM Pro allows you to open a scanned photograph (or another bitmap image) directly,

automatically converting it to a 3D relief . It does this by creating a Greyscale image of the

photo, and giving all the light areas high values and the dark areas low values . For this

reason, it is best to use a good quality image with plenty of contrast between light and dark.

Creating a 3D Model from Photo

Your chosen photograph could be

an image from a digital camera

a scanned image from a book ormagazine

an image imported from the internet

It must be in JPEG, Tiff or Bitmap format.

First click on Create Model from Image

In the Load Phtograph box browse to find

your photo, and click Open . - the 2D and 3D

View windows and the Set Model Size

dialog box appear:

Change the sizing method to Image

Size , and enter the required

measurements of your material in

the Height and Width boxes.



The Height in Z box allows you to set the height of your 3D Relief. ( typically about

2mm – eg. assuming material has a thickness of 3mm , a minimum of 1mm must be left

unmachined, so the relief can have a Z height of 2mm )

Click OK with the Left mouse button. The 2D View will now be showing a greyscale

image of your photo:

ArtCAM Pro has automatically calculated the 3D Relief for your photo and it is shown in the

3D View .

It is unlikely that you will want to use the whole image – and it is very simple in ArtCAM Pro

to crop the image as follows……

You can see how different parts of

the photo have been raised and

lowered.

Re-open the 2D view

Select the Polyline tool from the Vector toolbar

Draw a crop line around the area you want tokeep – (don’t worry too much about the accuracyas you can always readjust the line afterwards!)

Use the Node Editing tool to do some fineadjustments to the outline, by adding / moving thenodes, unitil you are happy with the accuracy.

Note: It is a good idea to make sure that SnapTo Grid is ‘off’ before you do this.





Smoothing the relief

The model may look a little rough in close

up – particularly if there are lots of areas of

light and shade in the picture.

To ‘smooth’ the relief, choose Smooth

Relief from the Relief Editing toolbar

And apply 1 smoothing pass to the model.

Saving the relief

This 3D relief could now be saved as a *.rlf file by using Save Relief in the Relief

toolbar – and added to another ArtCAM model – Why not give it a go!

The finished model

should now look

much smoother.
