how to combine hatch?

[Anonymous]

thx

Don't think it's a built in command unless it was added. I use this autolisp.

Hi @Anonymous,

Can you give me a better idea of what you are trying to do with the hatches? I don't know of a way to JOIN hatches but you could perhaps use Group or block to get them to "stick" together.

An alternative is to move one hatch, erase the other and then re-select the boundaries and apply a single hatch. Then you can match the original hatch.

Please show me an example of what you are trying to create.

HI @Anonymous,

Did the lisp provided by @gotphish001 resolve the hatch issue or did the more manual approach I suggested do the trick?

Please add a post with the status of your issue.

Thank you for sharing your problem with the community.

I think when you apply multiple hatching in the same area it will combine easily and it is easy to apply the hatch on an area and for hatching, you should use command HATCH then select the area where you want to hatch and repeat the same process again then you will get the desired output which you want.

Hope the above information may help you!!

Use HATCHGENERATEBOUNDARY , it will create polylines for selected hatches , then use hatch command and select generated polylines , uncheck separate hatched box ,it will generate one hatch for all areas .
Hope this can help you .

it doesn't work for mac

Can someone help me?

It doesn't work for mac, because Mac can't use it.

Use autocad for windows.

[amandahgmartins]

Well... I think I wasn't clear.

Is there any lisp that can merge hatches FOR MAC?

I have a MAC, not windows.

Hi All,

I'm trying to do this too, but only becuase I'm wondering if a hatch will fix my problem.

I've got two construction boundaries, one is approved, the other is a nice to have... and I want to splice them both to create one boundary taking the outermost areas. I tried merging the hatch, and then recreating the boundary but that then just created two boundaries which is what I had at the start. Any ideas?

The blue line is what I am trying to achieve. ie, to merge two closed polylines.

STEP 1:

type generateboundary and select all hatches at once.

STEP 2:

erase/move singular hatches (you can type selectsimilar and move/erase them)

STEP 3:

type hatch and se (select objects)

STEP 4:

Select all boundaries created at step 1 at once.

This method is quick enough for me.

@gotphish001 ,

That is a masterpiece by By Juan Villarreal.  Just what I needed for merging adjacent hatches of impervious surfaces lest I miss any when taking off areas.
