Constraint Problem

Open the attached cabinet in the Cabinet Editor
Go to the Constraint Manager
Apply constraints from the top of the cabinet to each of the five flutes (should be 4")
Exit the Constraint Manager and apply constraints
Hit the keyboard esc to de-select the part
Select the part and return to the Constraint Manager
Top constraints are gone.

I am getting these same results!

Kerry, does it make a difference that these cuts are not geometries and that they are profile cuts?

John,

I don't know. It seems in the past I was able to do this but I don't remember. I need some way to create a fluted pilaster that can change size easily.

Hi Kerry,
I've done this two ways:
For both options, the first thing I do is set up a tool with a slightly smaller diameter than the flute being cut, by say 0.005"

The constraints usually hold for pockets. This is the constraint method - make the pockets on a cabinet back and constrain. Set up one pocketing tool per above and have at it.

Another option is to use a dado which cuts better and will be more efficient machining.
You can use phantom partitions with top and bottom insets for control (and this is very easy to change). You could also just change the thickness of the phantom material for different width flutes, and you can change the "full dado" depth from partitions to the cabinet back to control the flute depth. Very flexible. Both can be done on a global level in the CE then that cabinet saved as a seed to add to a batch list. Machine with tool setup above and set to conventional cut.

The reason I like the dado is it grazes both edges of the flute with only the necessary amount of machining and now that the ramping for dadoes is fixed (thank the good lord) it is very efficient and produces the best result with minimal cleanup after the machining.

Hopefully I have not rambled on about all the things you already know.

Josh,

I will have to try one of your ideas. (I remember your post earlier about using the the blind dado) but I still feel this should be fixed.

The point of the Part Editor and Constraint Manager is to easily create parts like this. (My parts are cabinet backs so they can be re-sized) I want to add these parts to Quick Cut. It would be great to set my hold down fixture and fence, select and size a pilaster in Quick Cut, place the precut blank on the fixture and go. Anyone can do it. (I know that a part created with your methods will work but I think there is something broken here)

Kerry,

There seems to be an issue with certain stand alone profile cut paths and the constraint manager. I will get this listed. I have attached a cabinet that is done via .005" deep pockets first, then I did a profile cut path "single" on one edge, comped left or right depending on which single edge I selected, then I plunged my tool .255" deep (to make up for the pocket depth). Now, you can constrain the pockets and the profile cut paths stay linked to the pockets by default.

Kerry, the only thing I forgot to mention if you try the dado method is that a dado operation will overcut the boundaries of the geometry by the radius of the tool so this must be accounted for (before the flutes are all too long....)

Thanks Josh, Scott,

Scott.

Your method does not allow me to apply constraints along the width using formulas. ( W/2 for the center flute and (W/2)/2 for the others) The pockets show and are not positioned properly because we are not working off centers.
I will have to create these on a part by part method until the Constraint Manager is fixed.

Kerry,

Try changing the width on this one and see if it does what you are wanting. I did not realize you were wanting to adjust it in the width. I think this should do it for you. Remember you can do things like {w/2-.25}.

Scott,

Now your just showing off.

You know that in the time it took to create these parts for me you could probably have fixed the Constraint Manager.

What if I want to trick the machine to change flute size and put a 3/4" cutter in place of the 1/2" without re-drawing the part?

Josh Rayburn · Post by **Josh Rayburn** » Fri, Jul 15 2011, 10:15AM

Kerry,
You can do it with a cabinet back and partitions that are .010" wide(thick) NO CUT material, set up T20 or whatever in tooling setup to be 0.005" diameter and you're done. Doesn't matter which tool is really in there, it's just gonna drop in the middle of the 0.010" rectangle, and move over .005 and graze the other side, then it's finished. No changes.

I'm just having a problem with the downloaded part. It seems to be two pilasters and they are a single entity. You select one and the other selects also. I had to go to the Display Part Editor and name the file just to make it act somewhat normal. When I opened the file straight from your file the pilasters were smaller than the target origin and I found it inside it.

I assume I need to associate it with a cabinet because I cannot get it to go into the constraint manager with out an error that it isn't a cabinet part.

Leo,

Is the problem with my original download or one of Scott's

The pilaster is just a cabinet back.

I get an hsf file and it is two pilasters about 18" apart, one in front of the other.
