What Happens After You Send Us a Sketch, 3D File or Mood Board

Samtop typically provides an engineering evaluation within 2–5 working days, depending on the level of detail in your concept. You’ll receive structural suggestions, material recommendations, and a cost estimate.

🎯 Introduction: You Sent the Concept. Now What?

If you’ve submitted your:

✏️ Sketch
🖼️ Mood board
📐 3D CAD file
💬 Email with idea

You’re probably wondering:

  • “When do I get feedback?”
  • “Do I need to prepare more details?”
  • “Is this going to take weeks — or just days?”

At Samtop, we move fast — without sacrificing precision.


⏱️ Average Evaluation Time by Concept Type

Concept TypeEvaluation Time
Hand sketch or mood board4–5 working days
3D model (STEP, Rhino, DWG)2–3 working days
Complete spec + materials1–2 working days
Repeat project / slight revision1 working day

This includes:

  • Feasibility review
  • Material plan
  • Assembly suggestions
  • Cost estimate range
  • Sampling approach

🛠️ Samtop’s 4-Step Engineering Evaluation Workflow

StepActionDuration
1️⃣ Review & ClarifyCheck visuals, dimensions, and brand intent. Fill in missing details.1 day
2️⃣ Material + Structure PlanRecommend materials, weight-bearing options, LED routing, etc.1–2 days
3️⃣ Structural ProposalProvide drawing, materials, tolerances, and cost estimates.1–2 days
4️⃣ Approval + Sampling PrepFinalize details and move to prototype.Same day approval

🧾 What Files Can You Send to Start?

✅ We accept:

  • ✏️ Hand sketches (even napkin drawings)
  • 🖼️ Mood boards
  • 📐 3D files (.STEP, .DWG, .SKP, .STL)
  • 📄 Spec sheets: size, materials, quantity
  • 📸 Reference images of past displays

💡 No 3D? No problem. We help build it from scratch.

🔎 Factors That Speed Up (or Slow Down) Evaluation

FactorImpact
3D model provided✅ Speeds up CAD processing
Confirmed quantity✅ Enables accurate cost estimate
Material defined✅ Avoids rework loops
Repeat project✅ Fast-tracked evaluation
Complex lighting or mechanisms⏳ May add 1–2 days

📦 What You’ll Receive from Samtop

Once evaluation is complete, we send:

  • 🔧 Engineering suggestion (PDF / 3D snapshot)
  • 📋 Material & finish list
  • 💰 Cost estimate by quantity
  • 🧪 Sampling timeline & plan
  • 👤 Project manager + engineer assigned

📌 Not just a quote — a real structural plan.


❓ FAQ: Engineering Evaluation at Samtop

Q: How long will it take to get a cost estimate after submitting my idea?

A: Typically 2–5 working days depending on your submission. Full 3D + specs = faster turnaround.

Q: What if I only have a sketch or mood board?

A: No problem — we interpret sketches and build engineering plans based on your vision.

Q: Do I need to send finished files?

A: Not necessary. We accept rough visuals, and our team will guide missing parts.

Q: Is sampling included in this evaluation?

A: We include a proposed sampling method, cost, and lead time — so you know what’s next.

Q: Can I fast-track an urgent project?

A: Yes. Let us know your timeline — we can prioritize based on your launch schedule.
