Prior to the Parametric Modeling release, the projection feature was extremely versatile: you could project parts of one sketch onto another, faces/edges of bodies onto sketches, edges of bodies onto other bodies, etc. Since that update, there are at least two scenarios that no longer function as before.
#1 — Projecting a sketch onto a sketch
If you take any aspect of one sketch—it could be a single line, a shape, anything—and project it onto an another existing sketch, Shapr will create a third sketch:
Prior to the release of Parametric Modeling, the sketch that was the target of the projection would receive and retain that new content; not create another sketch.
#2 — Projecting parts of a body onto a sketch
If you take an edge or face of a body and project onto an existing sketch, that target sketch will no longer receive that projection. Like above, a new sketch will be created:
Fortunately, projections from sketches to bodies (as edges) still work, as does projections between bodies (as edges).
The two scenarios above are used daily in my work. My projects are often extremely large—hundreds, if not thousands of bodies and sketches—so this approach gave me great flexibility to add reference lines of other sketches/bodies into existing sketches. I’d often convert those into “Construction Lines” so I can measure and/or build upon those for a particular piece I’m modeling within my large project.
I’m hoping this isn’t an impact from the new Parametric Modeling update. If so, we’re technically no longer “projecting” onto items in the two scenarios above. If this is not defect, does anyone have recommendations how to bring in edges and faces into existing sketches?
Thanks or the reply, @Istvan! I truly appreciate your help, but I don’t fully understand “sketch mode” in this specific context:
…you just need to initiate the project tool from sketch mode
If I’m actively within a sketch (i.e. I can see the line, arc, spline, etc. options), I can’t project onto a different sketch. In fact, the other sketch disappears from the item list:
Unless you mean to ensure “Edges” are not selected as an option when projecting overall. In the two scenarios from my original post, “Sketches” were selected:
Select the sketch into which you would like to project another element
Select the Project tool under the sketch menu
Select the elements youd’d like to project
Since now you can have multiple sketcches on a single plane (which was one of the top feature requests), this is how you can tell Shapr3D to add the projection to a particular sketch.
You are selecting a Face, not the sketch itself. Try selecting the sketch from the Items list. You will notice the the Projection tool now is labeled with “Sketch”

Hi @Steve! When selecting the sketch itself via the item list, I get the same issue as described in my first reply, above. A projection option appears; however, the other sketch I’d like to target disappears from the item list.
@Steve you’re not able to reproduce this issue with the latest version?
Selecting whole sketches aside, I’d very much like/need to select parts of a given sketch to project; not the whole thing. This feature was available prior the latest release.
Not a problem. You can individually select whatever you want, including edges of bodies, etc.
I suspect you are not performing the correct order of actions (muscle memory can be annoying ) As long as you select your desired Target sketch plane first, then let Shapr know what you want to do (i.e. project sketches), then you should have complete flexibility on how much or how little you want to project.
FYI, on the iPad Pro, I tend to select the source sketch (or face) then the destination plane (or face) then I select Project. I use the same method with Replace Face.
You are more than welcome. I love solving problems, because I usually discover something new along the way.
In fact, I think you helped me discover, if not a bug, at least a quirk. I did some more exploring with an older drawing that was created before the history release. In hindsight, it makes perfect sense, but was pretty confusing until I figured it out.
If you select a Target sketch plane that was created pre-update and try to “Project Sketches”, then all other sketch planes “disappear” and you cannot project from them. I guess this is a holdover from the past when only one sketch plane could exist for given spatial plane.
Newly created (post-update) sketch planes work fine and you can project from any of the “original” sketch planes, so, if need be, you can recreate a new, modern format sketch plane with any desired sketch elements.
This might be a defect if you’re saying it still should project directly onto an existing sketch…

This was the lightbulb moment — thanks
