Too many unknowns in a single group (by David)
Hello,

Sorry if this a noob question. I´m totally new to all of this...

Please see attached image, i need at least three more of the triangle rows.

But as soon as i copy & paste them i get the error "Too many unknowns in a single group!" And can´t go on.

How can i solve these unknowns ?

Thanks in advance !

If these are all identical and evenly spaced, you may try sketching the first 2 and then using new-group step-translating to create the rest.

I think your sketch has too many free parameters for the solver?

Hi, this works for one additional row, but if paste it again the same error appears.

For my understanding, what did i make is an unknown ??

The expected way to use SolveSpace is with many small sketches in multiple groups. For example, you could extrude the overall outline, and then cut the triangles. That would also be a lot less work, since you could use parametric step and repeat as Paul says.

David, attached is an example of how to create those triangles, assuming that they are holes in a sheet. Because you have an odd number in the rows, you will have to create a row with ab even number, and add the final column separately. However there are NURBS issues, as noted below for Paull to add to his collection,if they are not already present

The g007 extrude works if its is constrained in length to the opposite face. Alternatively force NURBS surfaces to triangle mesh at this point. The gooa_extrude can only be made to work by forcing NURBS surfaces to triangle mesh. In playing with this, there a re no problems with extrudes after goo4_sketch. An extrude after the g005-translate has the 'interesting property that the NURBS problem comes and goes as the extrusion length dragged up and down. This is using version 3,9 under Manjaro.
