Apr 21, 2024 · The Sketcher DeleteAllConstraints tool deletes all constraints from the sketch. Clicking the underlined text will select the conflicting Jun 26, 2015 · You could remove Constraint 29 and use equality constraint on both arcs but as said using coincident constraint in the first place probably makes more sense. I was using 36 constraints for a simple sketch with 4 lines and 3 arcs! My issue is now gone, and I'm happy to consider this a gentle improvement in my FreeCAD skills in Sketcher Hi im new to modeling in freecad and constraints and i see in any video tutorial they have this 2 checkboxes under solver messages; auto remove redundants and auto update, mine has only this small renew button, i have version 0. I find the option useful, but some will suggest not to use it in order to better learn the software and for better control over which constraints are kept and which removed. 7 Qt version: 5. It just selects the constraint. There is also an option to automatically remove redundant constraints in preferences: edit menu -> preferences -> sketcher -> auto remove redundants. The place where it would be more useful is in the constraint list right click menu (where it currently isn't). 1. Optionally keep creating constraints. Select two or more edges with Horizontal or Vertical constraints, for example a rectangle. As you see in the solver messages section, constraint 5 is redundant, and FreeCAD won't allow you to add new constraints as long as the existing constraints are having issues. Notes. Setup. Deactivating constraints allows you to test other geometry arrangements without deleting constraints. 0a OCC version: 7. Run-once mode. Open FreeCAD, create a new empty document with File → New. introduced in 1. Sep 30, 2019 · I am struggling with selecting the origin when I try to do a dimensional constraint horizontal or vertical. The Solver attempts to reconcile supplied constraints to complete a final model. If such constraints exist in a sketch the Solver messages section of the Sketcher Dialog displays this message: Over-constrained: (#, #, #) Where (#, #, #) are the indices of the constraints. Hold down the left mouse button over the constraint value and move the mouse. So do as it suggests, remove constraint 5, and then your sketch should turn blue again instead of red :) Aug 26, 2017 · The tutorial casually mentions "If you had Auto constraints on, some of these constraints will have been applied automatically, if not, do the following". Dimensional constraints can be repositioned in the 3D view by dragging. Aug 29, 2022 · Click on the number next to the "over-constrained" text and press delete to remove the incorrect constraint. Close the sketch and use the Sketcher ValidateSketch tool in the Sketcher module. Build type: Release Python version: 3. The Solver will prompt you to remove constraints that conflict with one anther. There are several ways to invoke the tool: Select the Sketch → Sketcher tools → Delete all constraints option from the menu. Important observation that I didn't make before: the vertical constraint tool is selected, the cursor shows the red vertical line next to the arrow. Since I would like to get an understanding of how things work on a basic level, I would like to have the Auto constraints turned off and I have spent 45 minutes out of my hour actually May 4, 2024 · The Sketcher RemoveAxesAlignment tool removes the axes alignment of selected edges by replacing Horizontal and Vertical constraints with Parallel and Perpendicular constraints. The edges can then be rotated without losing their orthogonal relationship. If the message is still there after the Recompute, click the blue text in the error message and press the Delete key and that should fix the problem. Aug 7, 2024 · There is a general rule with constraints: the fewer amount of datum constraints (dimensions), the better. Learn how to remove a constraint in FreeCAD to modify your 3D design. Jun 15, 2024 · A Tangent constraint is added. Keep it in the menu (same as 'Delete Jul 24, 2018 · The sketcher solver advises you of redundant (meaning conflicting) constraints, you need to delete them before proceeding to fully constraining your sketch; then you need to apply constraints that will not conflict with existing constraints. See Examples. This is one of the most important things to understand when creating models in Apr 21, 2024 · Select the Sketch → Sketcher tools → Delete all constraints option from the menu. To finish, right-click or press Esc, or start another geometry or constraint creation tool. If I understand you correctly, you are saying, what I am currently seeing, is that when FC gets into a situation where the sketch is over-constrained, the ONLY way to fix the issue is to undo the change which caused the sketch to go into this state, which should bring the sketch back to a constrained state. Apr 21, 2022 · Deleting the listed redundant constraints ends up with a condensed list of constraints but the solver still asks for "Please remove the following redundant constraint: 8", but that constraint was already deleted. In this case the line has to be vertical. Do one of the following: Select two edges (see above). There look for missing coincidences and fix then automatically. It looks like a fault in the solver, but as a complete newbie to FreeCAD, I guess it's my fault. jpg Then change the constraint type for AxialAlignment_ConnRod-Piston to PlaneAlignment_ConnRod-Piston (rename the constraint after change of type). 3. Reposition constraints. 0 May 9, 2019 · Hello, i'm running freecad 0. I get the no entry sign when I move my mouse over the origin point but if I move away a little bit I get the constraint symbol. May 4, 2014 · In the meantime, the "auto remove redundants" mode (you will find it next to the solver messages, a checkbox) have been merged. It is preferable to use a geometric constraint in place of a dimensional one if possible. First of all remove the constraint "PlaneAlignmentV_AxleBox-CrossHead (whith offset)" that I had used to position the piston mechanism. 18. So I suggest removing it from toolbar. 0. There is no automatic prompt to edit the constraint values. So there is no need to constrain it vertical. May 7, 2024 · The Sketcher SelectConflictingConstraints tool selects the conflicting constraints in the sketch. Result: Now I can't delete any constraint. Only 7 constraints are shown. 18-16110 and i try to fillet a rectangle whose size is constraint by distance constraints on its edges. The Delete All Constraints dialog opens. Feb 14, 2021 · As I am still learning FreeCAD, I decided to remove my constraints and re-constrain, as I've learned better ways to constrain things in the intervening months. As you didn't post your FreeCAD file, I can't say why they are redundant, your screenshot does not Jul 23, 2024 · The Sketcher SelectRedundantConstraints tool selects the redundant constraints in the sketch. Pressing delete deletes it correctly. In FreeCAD, learn how to add and remove coincident constraints while sketching. Jan 27, 2025 · Double-click the constraint in the Sketcher Dialog.

I've noticed that when i use the fillet on this rectangle, it makes the edges disapear and thus the constraints on the size of the rectangle are broken (you can see that as you change the fillet radius, it changes the size of the rectangle). The line with 5mm length starts at the origin and is 5mm long and has a tangent constraint to the y-axis. relative to the origin. 0: Right-click in the 3D view and select the Delete all constraints option from the context menu (not available if there is a selection).

By clicking first on the vertical constraint button in the toolbar and then clicking the line. May 13, 2024 · Thanks for this. Right-click the constraint in the Sketcher Dialog and select the Change value option from the context menu. Now add a vertical constraint to the line. Delete all Geometries is not. It was quite a request to do something so that redundant creation did not get in the way while using the sketcher (specially when using the polyline creation tool). Invoke the tool as explained above. What I am I doing wrong? Is there a setting in draft or sketcher that needs adjusting. The solver is not perfect so be cautious removing constraints. adp rukq inri qpry eawq wicr lewelu aomlkg jdehgs glbxra gtcn eiurt yybpu mbkkp utp
