Unsymmetric Loft - only solution to loft half and mirror?
So I've been trying to create a forward fuselage for a RC aircraft. I've got a decent amount of time working with lofts, especially with make wings and alike. however with this particular problem I'm running into the loft generating unsymmetrically, I've been playing around, trying different sketches, matching up each…

Improve surface of complex shape
I try to create the head of a fantasy panda. The result is not as smooth as I wanted it to be. So I'm asking you if you recognize mistakes or space for improvement. For that I'd like you to quickly guide you through my process: I started with this sketch. The head consists of two splines. I made sure the had the same angle…

Is there an easy way to achieve this plane?
So I see that the tangent plane feature seems to only work with cylinders which seems quite limited. I would love to get a tangent plane to a general curved surface. It seems like if I make a minimum bounding cylinder, make the plane around that, then suppress that part I could get the desired plane, but I also cannot…

Tolerance for Boolean Add Along Surface Edges?
Is there an accepted way to compare two surface edges to see if they are within tolerance for a boolean add operation? I'm trying to create an approximate offset curve along a surface - within tolerance - so it can be used for trimming and other operations. In this image the input curve is an isoparam (degree-3) and the…

How to create Tangent Complex Curves
I'm trying to create a single shape - but one with complex curves: A 'rounded heart' shape. I believe the construction should be relatively straightforward, as the object is symmetrical front/back and left/right I believe the intended way to create such an object is: * Sketch the silhouette of 1/4th of the object from…

How would I do this twisted surface that makers muse did?
Makers muse recently did a video Going over Surface modelling in CAD using fusion 360 and said that most of this is applicable to Onshape as well. I wanted to follow along with the tutorial but I'm running into this issue immediately because onshape doesn't have the tool highlighted in red. So How would I make this twisted…

Sweeping a profile around body while keeping profile normal and tangent to face of body?
I can usually figure this stuff out but this one has me stumped. I have a revolved body (a spindle of sorts) and I'm trying to cut a V-notch the length of the spindle, while that notch rotates 3/4 away around the body. I've tried several ways, but none of the ways seem to get me what I need. I've looked around the forums…

How to Create a Surface with Gap in OnShape?
So I have this boundary with three sets of airfoils inside them and I am trying to create a surface wherein this entire boundary acts as the domain and these three airfoils remain as the gap. I have to export this surface to Ansys later on for CFD analysis of these three airfoils so I am having an issue using the Fill…

Create a solid part from Surfaces/Composite Parts
Hi all, I have a surfaces/composite part model that I want to turn into a single solid so I can create cut outs. Anyone know how I can do this? File is below. Thanks in advance https://cad.onshape.com/documents/21b70d3354c4cef991db9e6f

Can you Fasten a vertex to a surface?
I have a relatively simple surface (floor) and would like to "triangulate" it with a set of triangular parts (tiles). See porch+walk | walk last mile question I'd like to model this to see how big I can make the triangular tiles and still get a reasonable walking surface. I've been manually fastening these together and…

Enclose Surfaces Question
So I have created a cover for a model boat motor. I am very new to surfacing, so I'm sure there are better ways to accomplish this. I got roughly the shape that I'm after. At that point I'm actually just trying to thicken it to 5mm thick. I'm able to enclose it and turn it into a part without errors, but I can't get all of…

Keep edges when extruding split line as surface
Does anyone know how I can keep the edge when extruding a sketch with a split line as a surface? Here is an example of what I am talking about:

How do I create this spout
I've been playing around with this for a while and made some progress but nothing that will work properly so far. I have a revolvled sketch which creates the bottle shape and onto that I am trying to add a pouring spout. I have sketched out the top shape and the side profile. I was trying to wrap the shape onto the surface…

Approximate Face (New Custom Feature!) 🆕
. CADSharp has sponsored a new custom feature: . Approximate Face This feature uses Onshape's new constrained surface functionality to re-create an approximation of multiple faces. Useful when working with features like Texture or Attractor Pattern that only allow one input face. CADSharp Feature Library . ⚠️ Need custom…

Create surface from perpendicular sketches? (making 3D printed mask)
Hello people, I quickly drew up these two sketches for a snake design mask and would like to know how I could possibly use both to form a surface which I can thicken later? Image below should hopefully explain better: The front plane sketch is the main front facing design, and the right plane is just one spline sticking…

Why does this Ruled Surface fail?
Hi onshape forum! I'm trying to create a ruled surface and it fails. I cannot figure out why it does and I'm currently unable to figure out a workaround. I'm referring to the last feature in this document (a simplified recreation of my issue):…

Non-Hybrid Modeling
I am a professional engineer with over a decade in modeling experience on multiple platforms (solid edge, solid works, Inventor, and Catia). A large part of my experience with complex modeling was using CATIA with which I excelled with robust design models. During this time, I almost exclusively used what I have come to…
