LogoPress warning regarding “nasty” sketch elements

LogoPress has added an extremely helpful warning regarding Splines, Ellipses & Parabolas (AKA nasties). This new warning is displayed when validating the property manager of the Annex part if it finds any nasties in the Blank section sketch. (When creating the Annex part, LogoPress automatically creates the Blank section sketch and this is the sketch that is used to automatically or semi-automatically create the internal punches and the external punches. It is practically always very important for multiple reasons that this sketch does not contain nasties.)

Here’s how it works:

 

When unbent it looks like this

 

When you select Part preparation before strip starting to create your Annex part, and after you select your options in the Part preparation property manager and validate, you will see this warning dialog pop up:

 

It will highlight the nasties that are in the Blank section sketch and prompt you as shown and you should definitely answer Yes. At this point LogoPress will create a new sketch at the bottom of the tree that shows the nasties like this:

 

 

This is extremely helpful because it shows you all of the areas in your Reference part flat blank that need to be cleaned up. It is important to note that you should not clean them up here in the Annex part, but rather in the Reference part. Open your Reference part and roll back to just above the flat blank station mark as shown here:

 

Select the Delete face command in SolidWorks (Insert, Face, Delete…) and highlight the area shown below (always be sure to select the option Delete and Patch when working with a solid body) and validate to remove this nasty area in the part. Doing so causes it to be absorbed by the true radius to the right of this nasty area.

 

At this point you should roll to the end of the tree and do a CTRL+Q (SolidWorks forced rebuild) which causes the LogoPress body files to be recreated. Now open the Annex part, then select the LogoPress command from the pull down menu called “Update the stations of the Annex part used in the strip”. This will import the newly created body files and cause the Blank section sketch to get recreated based on the new, clean flat blank. Note that as you can see in the picture below the sketch at the bottom of the tree that LogoPress automatically created called “Sketch showing the splines on the flat blank” now has dangling relations in it. You no longer need this sketch so you can simply delete it.
