Re: How do i create an impression of a CAD model or invert the CAD?
Look into using the cavity tool. If you can post the part I will do a sample for you.

Re: How do i create an impression of a CAD model or invert the CAD?
Hi Greg,
I have uploaded the CAD here Par_00051425_CP - Download - 4shared
I'll have a fiddle with the cavity tool, i did try to create a cavity, but the orientation of the part it wasn't creating the split line where i wanted it, i want the flat 'A' face of the part to sit into a nest and the arm that leads up in an angle to also be supported, i was trying to create a block and just move the part into the block where i wanted it orientated and leave an impression, but nothings ever as simple thanks everyone i appreciate the replies

Re: How do i create an impression of a CAD model or invert the CAD?
If you have that as a part then create a block using extrude and don't merge it. Then simply subtract the body from the block.

Re: How do i create an impression of a CAD model or invert the CAD?
When Deepak suggests to subtract the body I think he is referring to the Combine feature using the Subtract option (maybe counter intuitive).

Re: How do i create an impression of a CAD model or invert the CAD?
Thanks Deepak, I tried extruding but it will only extrude flat surface and not all around the edges etc, i'm a complete novice to solidworks and don't really know what i'm doing, i thought it would be easier than it is, thanks for the help.

Have a look at the attached. If you show the hidden body and rollback the feature tree to see what I did. I used the intersect tool in this example.

arr thank you Greg I will try this now

Can you attach the file or screen shot show how is the part geometry.
Check #18 here on how to attach files here:

Hi Deepak,
Thanks, Attached is image of what i'm trying to do, i wanted to just push the impression of the CAD into a block then cut out little bits that I need access to with CMM probe, as below. The arm itself i could extrude down and the sides so that was perfect but the flat square base is slightly curved and it just wouldn't let me extrude, or rather i didn't know how to extrude something that's not a flat plane.

Re: How do i create an impression of a CAD model or invert the CAD?
You can use other surface to create the sketch and extrude. Can you attach the file here (instead of external link) and I can have a look at it.

Re: How do i create an impression of a CAD model or invert the CAD?
Step file attached, is this format OK? Really appreciate all the help, thanks

Re: How do i create an impression of a CAD model or invert the CAD?
Not sure but check if this is something that may help. You can modify the file further as required.
Added one more version with impression for the base.

Re: How do i create an impression of a CAD model or invert the CAD?
thank you so much, that's a great start for me, exactly what i wanted, i'll look through the features on yours and try and work out how you did that, and so quick, i've been on days with this already

Re: How do i create an impression of a CAD model or invert the CAD?
The uploaded files are not native SOLIDWORKS files but those are STEP files. I can upload SW2015 files if those can help.

Re: How do i create an impression of a CAD model or invert the CAD?
yes that would be a great help, thank you i'll 3D print the one you did for me on Monday when i'm back at work and i'll see how it works, i'll let you know

Re: How do i create an impression of a CAD model or invert the CAD?
Here is the 2015 version file. Please move the bar to end to see all features.

Re: How do i create an impression of a CAD model or invert the CAD?
If you've SW2015 version then you can increase the side height. I didn't kept it high as I thought you might want to measure from sides.
How much height you would need? I had kept it .25mm and now increase it to 1.5mm (same height as the part. Attached are both parasolid and SW2015 files.
