Build to Drawing: Send These Four Items for the Fastest, Most Accurate Quote
Send These Four Items for the Fastest, Most Accurate Quote
- ① Dimensions and Appearance — Outline dimension drawing, mounting method (floor-standing / wall-mounted / flush-mounted), ingress protection (IP) rating requirements, or a few site photos;
- ② Electrical Requirements — Single-line diagram, or at minimum the number of incoming and outgoing circuits, main breaker, and metering / power factor correction requirements;
- ③ Components and Functions — Component list (BOM) or functional requirements list; if you don't have a list, just describe what the cabinet needs to do and our engineers will work back to a solution;
- ④ Quantity and Lead Time — Required quantity, target lead time, acceptance criteria.
The more complete these four items are, the more accurate the quote. A single photo is enough to get started, but you'll get a price range rather than an exact figure.
Drawing Review: Not a Blind Build to Drawing
Drawings go through a review first, focused on three things:
- Manufacturability — Whether the structure supports efficient production (bending, welding, assembly sequence), with optimization suggestions where it doesn't;
- Safety and Compliance — Whether electrical clearances, creepage distances, heat dissipation, and ingress protection meet standards;
- Cost Balance — Whether there are alternatives that cut cost without cutting quality (materials, component brands, processes).
Every proposed change is explained to you up front and executed only after your confirmation — no unauthorized changes, and no blind build to drawing just to win the order.
Drawing Confidentiality (NDA) Policy
Custom projects often require seeing drawings before we can give an answer. If you're concerned about drawings leaking:
- Sign an NDA Before Sending Drawings — This is standard practice; you don't need to ask for it;
- Scope of Coverage — Drawings, BOM, process information, and all technical documentation provided with the project;
- Term and Effect — Effective upon signature and seal by both parties, covering the entire cooperation period and the agreed confidentiality term;
- Internal Controls — Project documentation is authorized on a need-to-know basis; access is limited to engineers assigned to the project.
FAQ: Common Questions About Build-to-Drawing Customization
Build-to-Drawing FAQ
What do I need to provide for a custom control cabinet?
Four things get you a quote fastest: an outline dimension drawing or photo, a single-line diagram / one-line diagram, a component list (BOM) or functional requirements, and quantity plus target delivery date. If you don't have a BOM, describing the functional requirements is enough for our engineers to work back to a solution.
What if I'm worried about my drawings leaking?
We can sign an NDA before you send drawings — this is standard practice on all our custom projects, not special treatment. The NDA covers drawings, BOM, and process information, and takes effect upon signature and seal by both parties.
Will you always build exactly to my drawing?
We review the drawings first. Where a detail is unsuitable for volume production or carries a risk, our engineers propose changes and proceed only after you confirm. We won't force a build to drawing just to win the order, and we won't make changes without telling you.
Have drawings? Sign an NDA first, then send them over
If confidentiality is a concern, we'll complete the NDA process before you send drawings. With all four items in hand, our engineers provide a quote range the same business day.
