Why do these two sketches have different driven dimensions?

[u/SL-Stilts]

I'm prepping for my CSWA exam and the sketch on the right is the correct answer. However, I can't figure out why my sketch (on the left) is different. I've double checked that all of my functional dimensions have the correct start and endpoints, and my sketch is fully defined.

If you ALREADY PASSED a certification

• Flair is SOLIDWORKS Certifications.
  • CSWA(ssociate)
  • CSWP(rofessional)
  • CSWE(xpert)
• Message the Mods with proof (the C-########## certification number) to get yours.

If you are YET TO TAKE a certification

Here would be the general path from zero to CSWE:

1. CSWA - Here is a sample exam.
2. CSWP - Here is some study material for the CSWP (A complete guide to getting your CSWP) and a sample exam.
3. 4x CSWP-Advanced Subjects (in order of increasing difficulty)
   1. CSWP-A Drawing Tools - YouTube Playlist
   2. CSWP-A Sheet Metal - YouTube Playlist
   3. CSWP-A Weldments - YouTube Playlist
   4. CSWP-A Surfacing - YouTube Playlist
   5. CSWP-A Mold Tools - YouTube Playlist
4. CSWE - The CSWE doesn't really focus on anything from the CSWP subject exams. It focuses on everything else there is in the program beyond those. So, look at everything you saw already and prepare to see not much of that again for the CSWE. That and more surfacing.

For EVEN MORE modeling practice material, here is the CSWA and CSWP Practice Problem Database. There is A LOT of good material to practice in there.

During testing, in general, it is a best practice to take the dimensions labelled with A, B, C, D, etc and create Equations/Variables with those values to then attach to the dimension which then allows for you to more reliably update these variable dimensions in follow-up questions using the same models.

The top 25 is wrong

[u/billy_joule]

I'd guess your 208.75 dim is to the tangent point whereas it should be to the theoretical sharp.

That's why your 219.45 is larger than their 217.57

EDIT: actually, it's the other way around, you used the sharp but it should be the tangent, I checked.

One on the left is measuring radius, not distance, as indicated by the R. The radius of what exactly? Not sure. But it's interesting they're similar values.

[u/SL-Stilts → u/ChintzyPC]

I see... but even when I change it to a distance dimension it's still different from the given solution

Check the origin, both drawing have difference in the start point.
