Hi all, The Rhino WIP provides the ability to create constraints. Constraints are a set of rules such as the length of a line, or angle between two lines, that are added to geometry. These allow you to build complex relationships in your model that are maintained as geometry is being manipulated. […

[image] eobet: But, it’s important that the MidPointConstraint has its own icon, so it’s easy to correctly read the entire sketch at a glance. Perhaps anytime you set any point along curve constraint to 0.5 it could change symbols? That’s a good idea. I opened the issue here for the icon.

[image] Joshua Kennedy: If you explode constrained curves the constraints should update so they reference the new exploded geometry. I also made this work so the constraints are updated when the Join command is run. The issue is here . My idea is that you should not allow this. If you explode …

Yes, thanks for the feedback. I’m in the process of handling your last big set of suggestions and this was one I am in the process of fixing. I opened the issue here .

Do you need to create a sketch to add a constraint, or will it be possible to do so directly on the 3D Geometry? For example, select a hole in an imported model, and constrain the diameter and distance from a face of the model? Alternatively, some provision to link an imported geometry feature to a …

will you add a warning if a sketch is over defined? I tested it to see if you added anything to prevent this or what would happen and it just crashes. it should show where its over defined or at the very least just prevent you from executing the constraint or dimension.

The current behavior will prevent adding a constraint if it detects a conflict. The crash also sounds quite bad but I cannot reproduce on my end. Do you have an example file with steps to reproduce?

if you create a rectangle you shouldn’t be allowed to dimension all 4 sides because if you change one of them it will be over defined. It looks like there was an update for rhino yesterday? I installed it and it seems to not crash now but it’s still allowing for dimensioning different sides and even…

I believe you should be able to add dimensions as you need them. The default behavior in a lot of parametric software is that a dimension will automatically switch to “driven” instead of driving. This is very useful, because sometimes you need the driven dimension as a reference dimension. It would…
