In order to create a “V-Form” progressive strip layout, one where the part is v-formed at the end of the die as the part is cutoff, you must use a split line in the middle of the bend and then you should unbend the part on each side of the split line. That is the key in order to have this v-formed part positioned correctly in relation to the flat blank.
Start with a dumb imported model for example (or of course it could also be a solid model that you’ve create in SolidWorks with SolidWorks features in the tree), with a single 90° bend in it, regardless of where the coordinate system is positioned.
- Rotate the model using the SolidWorks Move/Copy body feature to rotate the model so that the legs are at a 45° angle relative to the planes.
- Now insert your split line by showing your temporary axis on the part (View, Temporary Axes) and selecting this temporary axis and one of the faces and Insert, Reference Geometry, Plane and put a plane at a 45 degree angle between these two selections so that it is splitting the radius in the middle. Then Insert, Curve, Split Line to split the face.
- Then insert a Logopress3 Station Mark and name it “010—V-formed down” for example.
- Then do a Logopress3 Unbending by steps to unbend one half of the bend, being careful to select nearest the split line for the first pick so that the split line is the purple edge in the Unbending by steps Property Manager.
- After this is unbent, unbend the remaining 45 degree bend, again, being careful that the purple edge populated is the one that was the split line.
- Now do a Move/Copy body to move the flattened part up to where you want die level to be.
- Then insert another Station Mark and call this one 020—FLAT.
At that point you are ready to start Part preparation before strip starting. Note that if you envision what we just did, and slowly animate the unbending/the v-forming in your mind, the part is down and as it moves up towards die level the part gets unbent equally from both sides of the middle of the bend; precisely what you need for a v-form progressive die.

When you insert Standard Components (screws, dowels, springs, etc.) with Logopress3 using either our free SolidWorks Gold Certified 123GO or with our 123GO Advanced you will find some times when you are not able to make a flat-bottomed hole (or a counter-bored hole) as deep as you would like to. Another thing you wouldn’t be able to do is to make a counter-bore depth as shallow as you’d like to be able to do. For example, if you were going to be holding down a 1/4″ thick stock guide down with a 1/4″-20 socket head cap screw and you want that hole to be counter-bored some amount, you won’t be able to.
This is because Logopress3 “controls” these depths via a customizable setting in a corresponding csv file so that you don’t make something too weak by making this flat-bottomed hole or counter-bored hole too deep.
If you know that you want to make this hole or counter-bore deeper than the setting in the corresponding csv file (or make a counter-bored hole more shallow) there is an option at the bottom of the Property Manager for the standard component that you are mounting that you can uncheck. This gives you control as opposed to the software controlling it. Please see the picture below.

Starting with Logopress3 2010 SP1.3, the “Item Number” custom property name has been replaced with “Key Number”. This has been done to eliminate confusion with the SolidWorks “Item Number”, which is something very different from what the Logopress3 “Item Number” referred to.

If I talked about a SolidWorks Custom Property called “CompanyName” or “Weight” or “PartNo” you wouldn’t have to think very long or hard as to what the evaluated values of these custom properties would end up being since they are quite descriptive.
As said in previous posts, “NumberNomenc” is simply the name of a Custom Property that the Logopress3 Bill of Materials (BOM) module assigns, uses and automatically manages ”behind the scenes” so to speak, for the purpose of sorting balloons in an orderly fashion.
The American Heritage® Dictionary of the English Language defines the word “Nomenclature” as “1. A system of names used in art or science” and “2. The procedure of assigning names to the …”
So, by adding the word Number before Nomenclature, and then shortening it a bit, we get the name NumberNomenc which means “A systematic method of assigning numbers.“

You may recall from a previous post that there is a Logopress3 custom property named “NumberNomenc” and the Logopress3 Bill of Materials (BOM) module automatically manages this custom property for the purpose of sorting balloons in an orderly fashion.
In the past, most people have assigned their balloons to use the Custom Property NumberNomenc each time they insert balloons. But there is a way to automate this. Please see the picture below that is a screenshot from one of our Logopress3 What’s New documents.
(Note in the above “picture” the first sentence that says “Default Logopress3 item number settings for all future drawings.” This will be getting changed in the very near future to replace the word “item” with the word “Key” in order to eliminate any confusion with the SolidWorks Item Number, which is entirely separate from what we are referring to.)
The NumberNomenc Custom Property is, for all practical purposes, synonymous with the Logopress3 “Key Number” and this is the number that is used for the sorting of balloons.
In the picture above there is an important step that should be mentioned before number 1. That is, “Open a new drawing file”. Then, follow on to step number 1 “Click File, Properties.”
One final note: Of course the second set of steps that starts with “Open the default drawing template…” should have a step 5 at the end of it saying “5. Repeat steps 1-4 for each drawing template you will use with balloons.”
