The width of the formula depending on the height (by Alexsander)
Hi, sorry for bad English. I want to create a rectangle. Height may be different (I will write by hand in size) and width I want to have height+85 automatically. How write the formula in width?

As attached, two different ways.

Thanks! 'm sorry, I do not understand what to do, step by step.

The basic concept is that your width is equal to the sum of the lengths of two line segments, one with length 85 mm (by a distance constraint), and one with length equal to your height (by an equal-length constraint).

In the first example, those two line segments form one horizontal edge of your rectangle. In the second, those two line segments are construction lines, and we use two align-vertical constraints to force the edge of your rectangle to the desired length.

Let me know if you still have trouble.

Thanks. I understand almost nothing in the creation of drawings now with your program because of the language barrier. But I'm going to teach English. Please open Youtube Chanel. Example:

Please help me. Please make a video how to draw the rectangle with these parameters. The lower example in your drawing.

Have you completed the introductory tutorial, and the tutorial on constraints? I believe with that background, the steps should be obvious from the sketch posted above. Let me know if you still have trouble, though.

I can not get to make the holes and where the plane is lost, there was only a lattice.

Sketch in 2D vs 3d (by Eric S)
I think you're running into issues trying to defined constraints when 'Sketch->Any where in 3d'

try selecting 'View->Align to Workplane'.

BTW NeroCAD's Youtube channel is quite nice.

Your first sketch (g002) contains some stray circles, at the points that SolveSpace has marked with "contour is self-intersecting". If you delete those, then the extrusion in g003 will work, and the rest of the tutorial should complete as expected. Let me know if you still have trouble.
