That makes some sense thanks.

We have got it set up in the post processor or add the over size for the grooves but I like your way of being able to see it as well.

Thanks all for your help

Hi Joss,

To add the tool radius, use the sub-method Groove and OverSeize

For the links use double-back Nil then create zones and then use zone reference which would then give all the modularity

I change all cabinet link to Zone reference

and in this exemple move nil double-back for change Shelve Widht

All the best, Alex

Hi Joss, Ness is away this week. He’ll take a look at it too as soon as possible, and see if he can offer any further solutions. Thanks

EDIT: looking back through our records, I see you had a detailed discussion about a range of technical issues with Ness, and what was coming in version 7 of Polyboard. In light of this, it’s definitely best he replies on his return next week.

Thanks for your patience in advance…

The shelves obviously wouldn’t fit into the groove though as there needs to be the radius of the cutter. Hand cutting it out isn’t an option as it opens up so many places for error, making an error of 0.5mm here would look awful.

Is this something that is going to be changed? It seems like a fatal flaw in the program. It is to do joints like this is the only reason we purchased the programme. I even showed Ness some samples of units we have designed in different cab programs.

We need this option adding to Version 7 please.

Is there a way of putting a shoulder on a groove rather than using a mortise and tennon?

We are using a nesting 3 axis CNC machine and using V-Carve to write the G-Code.

In the example you show the shelf doesn’t got into a groove. We want this for the strength and accuracy during assembly. We don’t want the groove to be shown on the front of the unit.

Cheers

Hi, 

Exactly or tenon without “Shoulder” and you can activate “Apply rule to Surface split” 

May be you can do it as shown in the attached example

What type a CNC are you using?

Cheers, Alexandre

Does that mean we cant use the underpassing option because we are using the mortise and tennon link type?

How can we get it to work??

We often use Mortise and Tennon joints as a work around because we don’t want the grove to be seen at the front of the unit in most cases but want the strength of a groove.

In this example we can obviously set all of the front screws back 20mm but what the one of the fixed shelves was only 100mm deep on a 600mm deep unit? We want to getit to be flexiable so one rule works on any depth of fixed shelf.

Cheers for you help

Joss

Hi,

The tenons and mortise clash with the fixation links in the example you had attached

If you had installed our Quick Design library by default in the Polyboard folder on your desktop, in the guide folder you will find the file “Polyboard Quick Design Library Manual”

Further information can be found from page 26

It should be understood that parts are identified by convention, Overpassing OR underpassing from other parts

in this example Side overpassing Top and underpassing Bottom, and Shelf underpassing Side

These marks are used for fixation link 

when you create link between Shelf and Side , and using rules

n=underpassing or no priority panel

p=overpassing panel Or  priority panel

z=zone (internal)

Hope my english not so bad and that help you

Cheers, Alexandre

I thought we had got our head around the Overlay/Underlay options when applying rules but have got stumped again.

On the following simple unit (Also attached) we have got 2 fixed shelves. One of them is 21mm recess from the door.

Capture.JPG

When we add the fixtures rules, we have them set to be 40 mm from the beginning and end with a max distance of 225mm between the fittings.

This is working fine on the fixed shelf that is flush to the front but isn’t stepping the start point 21mm on the fixed shelf that is recessed. I have spent a few hours playing around with different ways to get it to work but I have failed.

We want it so the first through hole will be an amount from the front of the shelf no matter if it is recessed or not. Sure we are missing something obvious but cant work it out!

Also what does it mean on the drop down list for the rules for the reference for “Zone inside”. I understand overlay and underlay (I thought!) but not sure what the zone inside options means.

Cheers
