HATCH doesn't show area AutoCAD 2017

[agataglo]

Hello, 

I searched through this forum and I didn't find the solution to my problem. If you know where I can find it though, I would be grateful for a link. Anyway, please help me with the problem I have:

I use AutoCAD 2017. I have an object made of polylines, there are multiple fields and islands, and I need to find areas of each. I used HATCH to mark the areas I need to find. I used standard ANSI31 hatch. Some of the hatches show area and some don't. I tried recreating the boundaries, I treid closing polylines and it didn't help. I tried to get the area using PROPERTIES, LIST and AREA command. Please help me to get that and maybe tell me how to hatch objects in the future so the area will be easier to get. 

Sorry for my english, I am not a native speaker. 

I will be very grateful for any help.

Hi and welcome to AutoDesk Community,

all of this happened because of your unclean hatch and bad way of work if you see attached image (red circle) you will notice unclosed hatch with grips for nothing. to get AREAS you have to refill hatch again without texts inside hatch and without unwanted grips.

i make some of your hatch again as a sample and every thing is going fine ..

Good Luck..

Thank you so much, I guess the unclean work is a problem here indeed.

Can you please take a look at a different sample too? Here I don't see any grips and the boundary seems simple. I might be mistaken though.

In this sample I need the area of that big violet hatch. Not only does the hatch go through the closed polyline (?!), but also I cannot read its area 😞 So its a double problem. How to avoid it in the future? I am sorry for my lack of knowledge, I am still learning.

still you have to be more accurate and prepare your lines to serve you.these unreadable areas hatch get out depending on your way of selecting the area to be filled.

herewith your CAD drawing..

Thank you so much.

What is the best way of hatching? Usually I was just drawing a polyline and pick an internal point. As you could see it didn't work this time.

i was preparing a new post for you telling you that HATCH is very sensitive for any complicated geom or unclosed areas or duplicated lines.

because of this :

- you have to arrange your drawings with proper and exact named layers to follow.because with LAYISO command you will define any areas you need to be    fill with hatch.

- when you want to use Pick option of selecting area you have to remember that you have to put all the picked area in front of your zoom screen.

- in future when you have circles and arcs and alot of crowded lines beside your picked area try to LAYOFF or LAYFRZ them to fast your procedure.

i hope it's help.. and be always here in COMMUNITY to get more and more useful CAD information.

You are an amazing help. Thank you for being here and for your patience and knowledge.

Hi,

I am also working on the same issue. I need to get the m^2 of an hatch area but I dn't know how. I tried the following commands to get/create it in my properties

PEDIT
HATCHEDI
HATCHGENERATEBOUNDARY

FIELD

http://www.thesourcecad.com/three-ways-of-finding-area-in-autocad/
JOIN
REGION
HATCH
AREA

Until now my hatch does not have a Property Area. What do I have to do (generate boundaries, etc) to create the attribute area for my hatch?

Best regards,

Paul

HI,

post here your CAD drawing (only the lines that we need) and tell me exactly what is your need?

Waiting...

Hi @imadHabash'

This is a sample drawing I exported from Revit. I intended to find area covered by hatches. Currently i'm Generating boundary then calculating total area covered by the polylines. Is there a way to have area field in these hatches.

Hi,

would you please post your question in a new post so that you will get wide help from others also .

I've seen this happen plenty of times where there are no obvious discrepancies in the geometry used to build the hatch. Though I am using C3D.

Adding to this old thread based on the issues I was having.

I didn't find the other advice in here to help directly, but it got me analyzing what was different about my Hatches.

I was hatching a bunch of different plines in order to get a gross area. Field wouldn't work for area on some, but would on others. I tracked it to how I was applying the hatch using pick internal point in some cases, and select object in others. When I would pline a bunch of areas, then isolate the pline layer, the easiest way to hatch them all was selecting all the objects. But, you can't read area from the resulting hatch, no idea why. If you go through and pick an internal point on each object, the hatch is functionally identical in all settings I can find, but now reads area properly.

Hope that helps someone else out.
