However, when I make the hatch a pattern like brick the surface hatch appears. Ideally, I am trying to make the surface hatch a solid highly transparent hatch, but when I make all of these changes and refresh my elevations (I even have recovered the drawing, regenerated it, and regenerated the elevations themselves) nothing happens. Then, I have to go into the material definition and check the 'merge common.' checkbox. I read in Aubin's 'Mastering ACA' book that I have to designate a surface hatch to the material definition, make sure it is turned on in both the material display and in the elevation's style display manager. So my ultimate goal for my elevations is to merge the material definitions of each level's walls so that the top and bottom lines of the walls are not shown. If you don’t know how to save and load LISP program read how you can do it here.I am using ACA 2017. It’s a raw code, you need to save it to lisp file before you can use it.

If it still doesn’t work, it looks like you need to try other alternatives. You may try to simplify it and try to create it again. Sometimes it doesn’t work well when you have a very complex pattern. This is a pattern I created in few seconds. Select objects within the rectangle then save the pattern file. You need to draw new entity.Īfter you finish creating the objects, you can run this command. Apparently this method doesn’t work well. I tried to copy object to this location and try to convert it.

You need to draw what you want as pattern here. This command will create 1×1 rectangle at coordinate 0,0. Once you load the LISP program there will be two new commands available. It is a very convenient way to create a pattern graphically. This free AutoLISP program is available on Cadalyst. However, there is an easier way if you need to create custom complex hatch pattern. You can check this tutorial if you want to know how it’s done. But if you can’t find it anyway, it’s time to create your own custom hatch.Ĭreating simple hatch is quite easy.
