How to do cad to part alignment

Well since you are brand new, maybe you wont get beat up too badly here... Have you taken the Demon 101 class? 

I am not sure what you are trying to do though. 
Are you trying to have the bad model in the proper orientation before starting your program?
Have your machine automatically find the part and start measuring? 
Do you need to know how to create a basic alignment?

I go for the 101 next week so I will probably get my answers there but we have a part I have to get laid out by this week so figured here might be my best bet between reaching out to support. I have the cad model loaded into pcdmis, but when I do the alignment for it to pull the cad and the true model together I think I must be doing it wrong because the true measurements don't line up with the model at all. And yes, the main goal is to get it to where when I click on a feature in the cad model, I can tell the cmm to go measure it and it know where the part is

So if you need to know where the part is, are you familiar with the readpoint function? It's the quickest way to help your machine find the part. Aside from maybe manual probing.

Example here with the hexblock I put the readpoint at the center of a circle, and aligned to that readpoint position. Then it measures that circle, and you could align to that after. So you would execute the program from the readpoint with your probe manually placed there by you so that it can get it's position relative to the machine.

To insert a readpoint just type read in the edit window. Of  course after this comes your main alignments to control your 6 Degrees of Freedom

            ACTL/<0,0,0>,<0,0,1>,2.5
            TARG/<0,0,0>,<0,0,1>
            START ANG=0,END ANG=360
            ANGLE VEC=<1,0,0>
            DIRECTION=CCW
            SHOW FEATURE PARAMETERS=NO
            SHOW CONTACT PARAMETERS=NO

I agree with William.  If this part is a "one off" or low volume part, I'd say readpoint is the quickest and easiest.  If this is going to be a high volume part, and you have a repeatable setup, I'd suggest the manual alignment option.  Once the part has been aligned, if the setup is always in the same place, you could either use labels or mark the manual alignment features so the routine goes directly into DCC measurement once executed, eliminating the need for the operator to position the probe every run.

Start here bud, YouTube should be able to get your machine moving and some very basic stuff going. 
Once you have conquered your very first simple alignment as shown in the video then move on from there.

Thanks for all the help! A lot of info I haven't seen or tried yet. I am going to get started late day early morning depending on time frame and implement everything. I will get back and let you know if I succeed haha

Here's a video I made a while back which would get you started.

Program Mode | Automettech (jonwood54.wixsite.com)

Can i download this video and use it within my company?

Sure - is there a way to download it from the link I shared?  If not I'll have to have a dig around to find the original.

Must come with a caveat - the site it's on (Automettech) was from when I was self employed doing this stuff, I no longer am and work for Hexagon, so obviously the services and products I offer on there aren't available - but the tutorials and free scripts etc - knock yourself out.

That would be my next question, I am unable to download it from the source provided :)
