3D File Guidelines

A step-by-step guide on how to prepare STEP and STP format files for quoting and production with SendCutSend.

Upload a single body

Your STEP/STP file should contain a single, solid sheet metal body. Files with multiple bodies stitched together or assemblies will not upload successfully.

Solution

If your design has multiple bodies, please save each one into its own individual STEP/STP file. Then upload each one separately to our platform.

Upload a STEP/STP file that contains a single sheet metal body only

Upload a part that is aligned flat to a plane

The model in your STEP/STP file should have at least one stationary entity that is aligned flat to a plane. Bodies that are angled relative to planes may not be processed accurately.

Solution

Reorient your part so at least one stationary entity (such as the base on a part that will be formed) is flat to a plane in the drawing space. Be sure to check files for individual components from assemblies. If parts have kept their orientation from the original assembly, they may need to be adjusted.

Do not upload parts with dimensional features

We only provide 2D through-cutting in flat sheet materials at this time. Fillets, chamfers, countersinks, counterbores, or other 3D features will prevent your file from uploading. STEP/STEP files containing bodies with tapered or dimensioned edges will not upload successfully.

Solution

Please ensure that the body in your file has a uniform thickness and a face at all sheet edges before uploading. The part should meet SendCutSend’s design guidelines for producibility.

If you need countersinking, hardware insertion, or tapping services, please provide simple through-holes in your design where you need the operations applied. After you have uploaded your file and selected a material, you can add and configure these services before checkout. We’ll take care of the rest!

Set up your part with the correct material thickness

This part has a thickness of 0.525"

Parts designed with a thickness greater than 0.500″ may not upload successfully. 

Solution

Before uploading your file, please ensure that your design is using a sheet metal rule that matches the stock thickness you will select from our material catalog when ordering your parts. We have guidance on updating sheet metal rules in Fusion 360 and SolidWorks.

Upload a sheet metal body

STEP/STP files may not upload successfully if the model is an extruded flat pattern rather than a true sheet metal body. Please do not upload files that include mesh bodies.

Solution

If your design consists of an extruded body, convert it to a sheet metal body before uploading your STEP/STP file. This function is accessible in CAD programs such as Fusion 360 and SolidWorks.

If there is a mesh body in your file, you may be able to convert the mesh body to a solid body and revise the model to meet our criteria depending on your design software.

Upload the correct bending specifications

Your sheet metal body must use SendCutSend’s material specifications if bending/forming services are needed for the part. Designs with the wrong specifications may not upload successfully.

Solution

Set up a sheet metal rule with SendCutSend’s K factor and bend radius for the material.

This ensures that your part will be bent accurately; you can find the bending specifications for the material and thickness needed for your part here: Bending Calculator

Upload a valid STEP/STP format file

Your 3D file must be a valid STEP/STP format file and meet our criteria to upload successfully.

Solution

When saving your design be sure to check the final file for accuracy. Sometimes an export does not work and the file ends up with an invalid structure or completely empty. 

 

If your file fails to upload, please revise to meet the requirements listed on this page and in our design guidelines, then try uploading again.

If your STEP/STP file still does not upload successfully, please contact our Support team. Let them know which program you’re using to design your part and attach your file so they can take a look!
