We fixed this in the current V25.12 pre-release - www.pcblibaries.com/downloads ;

Let us know if this works OK for you.

I created a side concave footprint for a fuse. When I export to Altium the 3D symbol looks strange. The concave part is not on the outside?

Info datasheet.

Hello everyone,

As a new member, I wanted to discuss the benefits of using 3D models in PCB design. Visualizing your PCB in 3D can help with component placement and verifying fit within enclosures.

Why Use 3D Models?

  • Better Visualization: You can see how components fit together in 3D, helping with space management.
  • Design Verification: It’s easier to check for component interference and alignment.
  • Improved Communication: 3D models make it simpler to explain designs to teams or clients.

Tips for 3D PCB Design

  • Use Your Design Software: Most tools like Altium, Eagle, and KiCAD offer 3D views of your designs.
  • Check Component Placement: Ensure components are correctly placed before switching to 3D view.
  • Export to CAD: For more detailed analysis, export your design to 3D CAD software.

3D models help reduce errors and ensure your design fits perfectly in the final product. Let me know your thoughts!

Footprint Expert goes not put text in 3D STEP models. 

The component family is - Radial (Dipped) rect. - Capacitor, Polarized

You can change the color assignments for:
  • Primary Body
  • Default Leads
  • Pin 1 Lead
  • Primary Polarity
We recommend if you want the exact 3D STEP model with text, that you get it from the manufacturer.

Hello;

How can I create a 3D view of shapes such as a capacitor with the code DGH355Q5R5 in Footprint Expert?

The Nominal density level is the most popular in the commercial industry. 

Military weapons contractors seem to use the Maximum density level for 3D models. 

Least is never used by anyone.

These refer to the +/- tolerance of the feature:

Least = the minimum dimension 
Nominal = the midpoint between least and most
Most = the maximum dimension

Example 1 (symmetrical tolerance):
3.57 +/-0.10
Least= 3.47
Nominal= 3.57
Most= 3.67

Example 2 (asymmetrical tolerance): 
3.67 +0.000/-0.20
Least= 3.47
Nominal= 3.57
Most= 3.67

Typically the nominal value is the stated dimension where the + and the - tolerances are equal, as in Example 1.

There are 3 columns of dimensional data in the Footprint Expert component family calculators. 

Nom / Min / Max and when you select a Material Condition, the 3D STEP output will use the column of data that you select. The default setting is "Nominal" material condition.

Hi to all,

I cannot understand very well the meaning of the parameter Material condition (Least, Nominal, Most).
Which is the meaning of it? Which is the difference?



Is there any relation with the Density Level of the footprint created?
I mean, if I am creating a footprint with Most material condition should I choose the 3D Material condition as Most? 

Regards,
david
