Here you can see the problem in question.

connections are Symmetric

the problem seems to be amplified when i use guides, when guides are not selected in the loft panel, it's still there but more subtle. Any help is appreciated, Just looking for the most efficient solution.

CAD file can be found here. https://cad.onshape.com/documents/73f5e52c7cad43333afdd767/w/b8cd8c29abfaec27ec7a0fd5/e/c3056cfa1f1d228e0ff19388?renderMode=0&uiState=69f11ce111864741dd66f9b4

What is the reason that we select Dark Blue's edge and point before selecting Grey's edge in step 1?
What is the reason that we select Dark Blue's edge before selecting Grey's edge and point in step 2?

et cetera…

For what reason are the edges chosen in this manner? I want to understand why a single piece doesn't have all the Start selection. What is the best practice to making Bridging Curves? Is it similar to fastening a tire, tightening the nut across from one another in a star shape as if i'm evening out pressure?

I would really love if this part of the course was more clear on what effects my ordering of parameters will have, if any :).

I use the variables and expressions lesson from the Learning Center https://learn.onshape.com/courses/variables-and-expressions to teach my students about the proper use of variables and expressions. Last November I had no issues with this content but today we discovered as a class that the Creating and Using a Variable Studio exercise was not working as described in the lesson. We were able to download a copy of the document with no problem and then create our variable studio but it did not copy the variables from the studio over to the part studio for the large cup. When I duplicated the part studio the variables worked fine.

I tried this with other documents I had and experienced the same issue. After some trial and error I discovered that in order to get the variable studio to be copied to part studios I already had created I had to at a minimum reload the webpage which refreshed the document. This was tested on various computers in windows and chrome with same same results. The issue is the learning center assignment does not mention having to reload only going back to the TAB. I assume it was some coding done somewhere that does not have the screen fully refresh even though when you click from the variables studio to a part studio that was already created it shows loading studio data. This happened to most of my students today.

Here is a screen shot of what the introduction to CAD looks like:

6<z=<8 1

8<z=<10 2

10<z 3

I was trying to define a variable by nesting expression { ((#k>6&&#k=<8)?1:(#k>8&&#k=<10)?2:3) }, but to no avail.
Please advise.

Sincerly

I really believe I want to make CAD a skill. I need to learn the core items/tools/basic so I can make this a useful tool. If I want to learn the core/basic of CAD, where can I find the functions and its use and non use along with the prerequisites or using these functions? If you will, the boring humble beginnings?

I would like files to be shared with and editable for both accounts - How can I do this?

Students may need to make simple parts such as goBilda spacers, quad blocks, and u-channels.

Thank you,

I'm trying to loft a feature with start and end conditions set to none. Attached are photos of the desired result on SOLIDWORKS and my result on Onshape.
The front view looks fine but the right view shows curvature in the loft where there should be none.

Any ideas on how to have the loft connect straight with the lower part?

Going through the 'Introduction to Part Studios' course in the learning center, the exercises in both section 7 (Funnel) and section 9 (Rocket Guidance Reflector) seem to be 'collapsed' so that the images cannot be seen and the text appears only one line at a time (see below).

I have tried to refresh the page, sign out and back in again, and open the page on another browser.
It seems this is only an issue for these two exercises.

Any ideas?

"Use the Use sketch command to convert the edge shown with label A to the line on the sketch shown with label B." How? I can't find any explanation in the course notes.

I come from Fusion 360, where I got in the habit of using the "project geometry onto sketch" feature.

I figured I could do the same in OnShape, but it doesn't appear that "Use" is meant for the same thing.

Here are the problems i'm encountering when I use the "use" feature in OnShape:

• the projected geometry is unconstrained. For example, If I project the cross section of a hollow cylinder (pipe), the resulting square is made of lines with edged that are not bound together, and I have to add these constraints myself.
• There does not appear to be any way to get the "use" tool to project all the cross-section geometry of a body, only each of its faces on a per-click basis. Working with a pipe, I have to manually select the outser cylinder face, and the two flat faces on each side.
• When building sketch geometry anchored on the projected geometry, modifying the geometry of the body use for the projection often breaks the sketch. Constraints fail to resolve, and I often have to delete the proejction, re-project and re-contrain. This has led me to designing in a roundabout way, using "proxy" construction geometry. For example, instead of using the projection of a pipe in my sketch, I create a driven variable measuring the outer diameter of that pipe and then draw a construction line of with the value. I build my sketch geometry on this construction line as a proxy for the projected geometry. Then mate the original body onto that construction line so that everything aligns. My background is not in CAD, so maybe this is the expected process rather than using the actual body? It feels like a lot of extra boilerplate.

Are the above problems expected, by design? Am I attempting to use a tool that goes against bad practices? Is this simply an area when the OnShape team hasn't gottent around to making improvemetns yet ?

Here is an example design where I've experienced these issues:

https://cad.onshape.com/documents/73b4848809bc10499f437dec/w/1a292b706c06d4986e233158/e/59145b9630d13329bc5bb145?configuration=Connector_Length_Override%3D0.0%2Bmeter%3BList_9eop9BmzEuLZ1g%3DDefault%3BList_DRkxR6QuIfx5vb%3D_45_&renderMode=0&uiState=69401a787389764c8957ae1c

It's a pipe addapter that is build off of a configurable pipe section imported two, with a hollow loft in between.

My initial design use a projection of the two derived pipes in the "Inlet & Outlet Relative position profile" sketch, but this ketp breaking when I changed configuration (especially the pipe's Angle. Going between 90° an 0° would break often)

My account works perfectly normal both on these forums and on cad.onshape.com

Introduction to Sketching - (link) But there is no document. I don't see a means of putting a link as an assignment, nor do I see the ability to assign the course. I did manage to find something similar with a document, but I'm running into other courses I'd like to assign, but run into the same problem (i.e. Introduction to Part Studios (link))

How are other teachers here managing the content. Are you ignoring the OnShape system entirely?

Thank you.

I can already view my students/classes within the CAD section of Onshape (so I can see their individual documents, etc.). But I don't believe that this allows me to also see their progress in the learning center?
