Surfaces To Solid Using Projected Curves And Lofts Onshape You can use tangency at joining curves and try not to put more than 3 points in a splines (two is often enough). you can do a lot with constraints and the spline handles. the forum has many threads on smooth curves surfaces. here is one and a second one where @john p desilets has some great tips for splines & lofts. There are three ways to do this in onshape. let’s take a look: first, select the thicken command from the toolbar. then select the faces surfaces that you want to thicken and enter a thickness. just below thicken on the toolbar is enclose, which allows you to create a solid from an enclosed selection of surfaces and or planes.
Surfaces To Solid Using Projected Curves And Lofts Onshape The "right" way would probably use projected curves and build the helmet around them. this technique would be tricky to implement, but if you do it right would be awesome looking. another way, if you just want the contour details to pop, would be to to sketch a "contour", extrude it to the helmet, then use fillets to blend. Projected curve. the projected curve command allows you to create a curve at the intersection of two sketches. this can be particularly useful when you need to create a loft profile (or guide) that is not planar. simply select two sketches, and a projected curve will be created at the intersection. These are powerful tools used to guide your surfaces as you create lofts, fills, sweeps, and other features. splines and bezier curves can be used to drive tangency and curvature. Use profiles (sketch regions or sketch curves) and optional guide curves to define shapes that smoothly transition between them. create parts or surfaces or modify existing parts or surfaces. loft: desktop.
How To Properly Use Projected Curves And Apply Surfaces Onshape These are powerful tools used to guide your surfaces as you create lofts, fills, sweeps, and other features. splines and bezier curves can be used to drive tangency and curvature. Use profiles (sketch regions or sketch curves) and optional guide curves to define shapes that smoothly transition between them. create parts or surfaces or modify existing parts or surfaces. loft: desktop. Using the thicken feature, a surface is thickened to form a solid part. using the enclose feature, a solid part is created by forming a closed volume, where every edge bounds 2 faces. create construction geometry (split lines for molds, blending and bridging geometry together, supporting lofts and fills for matching curvature and tangency). The projected curve feature allows you to create a curve from the projection of two sketches (two sketches option) or from the projection of a curve on a face (curve to face option). note that the projections from one sketch must intersect the other (sketch or face) in one contiguous curve for this operation to succeed. Unlock the power of smooth transitions with the loft tool in onshape! in this episode of shifting to solids, we’ll guide you through creating complex, flowing 3d shapes by connecting multiple. I think i want to loft the "face" of the tram, and guide the loft with curves splines projected from horizontal and vertical views to get the profile correct. i had some success with getting a nice projected curve, but decided to replace a line with a spline on my bottom (horizontal) profile, and it's all gone wrong from there.
