itacad Posted July 9, 2018 Share Posted July 9, 2018 Hello, very often it would help me to draw hatchs with "net" style...it could be a false ceiling or an elevated floor, but I can't set the measurement of the square of the net...for example I need to draw an hatch with net style with measure 6 cad units for the "side of the square"...is it possible to set this parameter?

ReMark Posted July 9, 2018 Share Posted July 9, 2018 Your options are Scale or Spacing. There is no option for setting cad units in the hatch command. You would probably be better off the Array command or a custom lisp routine. Quote Link to comment Share on other sites More sharing options...
BIGAL Posted July 10, 2018 Share Posted July 10, 2018 (edited) You need to copy the NET pattern and call it something else and change the scaling numbers to 1 then you can draw a square any size you like by scale. In default the pattern is set to 0.125 as a length just change it to 1 and add to ACAD.PAT *NET, Horizontal / vertical grid 0, 0,0, 0,.125 90, 0,0, 0,.125 *SQUARES, Horizontal / vertical grid 0, 0,0, 0,1.0 90, 0,0, 0,1.0 Edited July 11, 2018 by BIGAL Quote Link to comment Share on other sites More sharing options...
eldon Posted July 10, 2018 Share Posted July 10, 2018 I had this problem also, so I created a pattern file of squares of unit sides. Now I can confidently create a grid of known spacing using the Hatch scale, and position the Hatch origin to align it where I want. *TILE11, 0, 0, 0, 0, 1 90, 0, 0, 0, 1 Quote Link to comment Share on other sites More sharing options...
itacad Posted July 10, 2018 Author Share Posted July 10, 2018 Thank you very much, I tried but I did not succeed. For Bigal: if I put your hatch in the acad.pat file, then I do not see it proposed in the menu. For Eldon: I created a test.pat file with your hatch, but when I select the file in the menù, an error message appears... Quote Link to comment Share on other sites More sharing options...
BIGAL Posted July 11, 2018 Share Posted July 11, 2018 It may be my fault left the * off the *squares. This may be beneficial if you want to keep all your custom patterns in one file. https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to-install-custom-hatch-patterns-in-AutoCAD.html Check also for extra copies of acad.pat Autocad loads the 1st one found defined in the search paths.

itacad Posted July 18, 2019 Author Share Posted July 18, 2019 Hello...In the meantime I found a fairly easy way to solve the creation of a 60x60cm ceiling with the hatch command... MODEL ANSI37 ANGLE 45 SCALE 1.89 (for drawings with a scale of 1: 100) I have a problem...the hatch created is symmetrical in the vertical direction but not in the horizontal direction ...it is also possible to make it symmetrical in the horizontal direction?

BIGAL Posted July 19, 2019 Share Posted July 19, 2019 (edited) The reason your doing 1:89 is that Ansi37 is based on 0.125 not 1 you need to go back like 40 years and look at how ANSI patterns were described. 0.125 is 1.8" Again change 0.125 to 1.0 make a custom hatch. 1/.125=8 so 1:100 is ten times 1:80 would be correct.
