Removing the outer square of a photo, Leaving 3D image?

I have important a 2D color photo into Aspire and then used the "Create a component from the select or bit map" to converted it into a 3D carving. The image was square, so I used the "trace bitmap" option to trace the drawing inside the picture. My question is, how do I remove the outer square box of the original photo and leave a 3D component of the picture on the inside that was traced? I just want the picture, and not the square box around it of the original photo to work with, in a 3D formate. My hope is then to take that inner traced 3D picture/component and place it in the bottom of a dish that I am carving using "create a shape from vector outline" option. Thanks in advance

As the background of your image is white, you don't have to bother.

The only issue is that the image quality is low, so you have some "not so white" pixels in the surroundings of the picture.

You'll have to adjust light and contrast to get rid of that and get a better 3D conversions. You may also want to invert the picture. Working in greyscale rather than color helps appreciate the settings effects.

The new image editing features in V9 allow you to do that without an external image editor.

If you still have issues with that, let us know.

If you want to create a 3D relief from a bitmap you shouldn't import it first via the Drawing tab. That option is meant for tracing and Aspire does some internal processing of the bitmap for those purposes.

That may lose detail if the aim is to make a relief model instead. Use the Create Component from Bitmap tool on the Model tab and load the bitmap directly from the open dialog that will appear if no bitmap is pre-selected.

To specifically answer your question, since it does in fact import as a square component, here's how I'd do it.

1. Import the bitmap, then use "Create a component from selected or imported bitmap" to create your component
2. Turn off the bitmap layer. You don't need it any more.
3. In the 2d view, select the component you created.
4. In the Drawing tab, click on the Trace Bitmap tool.
5. I chose the settings as shown in the following screen:

6. Select the vector you just created, and also select the component. On the Modeling tab, click on the "Clear area of selected model outside selected vectors" tool

You should be left with just the shape you want.

Hello sir
I am a high school engineering teacher from Northern Indiana and am using Aspire with my Probotix router.
I too have the same problem. I followed dealguy's directions but ran into a problem and was wondering if you could help.
When I push the "Clear area of selected model outside selected vectors" button I get this message....

Invalid selection
You must select at lease one component & one object to trim it with.Trimming vectors must be closed.

I have enclosed as many pics as I can think of......

I am not sure what I have done wrong.
Please help

Are you sure you selected both the vector and the component at the same time? The message is saying you didn't. Click on one to select, hold the shift key and click on the other. They should both change color to indicate they're selected. Then do the trim.

Hello sir
I am trying to figure out which things exactly to click. I tried the vector and the colors both but I keep getting the same response. Is there a way you could give me a couple of pics of this or a very quick video of the steps? I know you are probably really busy and don't want to be bugged. I would really appreciate it if you could help.
Thanks for getting back to me.
Again, I really appreciate your time

In the trace tool, make sure you clicked "Preview" to create the vector, then "Apply", then "Close". You should now have a 2d view that looks something like this, with a component and a vector:
Trimming example 2d view.JPG
There are no colors any more.

Now select the component and the vector. The component should go dark and the vector red in the 2d view:
Trimming example items selected.JPG
Finally do the trim, and you should be left with a component something like this:
Trimming example component 2.JPG
Now you'll need to work with a zero plane and other modeling tools to get it to look like you want.

Thank you
The problem is that when I click the vector it turns red but when I then click the component the red goes away. This happens when I reverse this. I have tried ctrl then click but the same happens.
I now see I where I need to click but just need to get them to both stay clicked. Any suggestions?

Again I really appreciate you taking time to help, hope I am not taking away from your business.

Hold the shift key and click one of the objects (vector or component). Continue holding the shift key and click the other one. Both should select.

WOW!!!!
Thank you Thank you Thank you!!!
I really appreciate it. It worked like a charm.
This will get the kids going.
If you have any pics of what you have made for your business with the router I would like to see them and show the kids.

The kids and I thank you again
