Threads in solidworks

[mcdescha]

I'm constructing a bulk head fitting and i need to make an outside thread on the fitting...does anyone know how to do that. i tried adding a cosmetic thread to the extruded part of the fitting but i have no luck and don't know what else i should do! any help would be great!! thank you

The best way is to draw the threads then revolve. Will be close enough looking like thds. Thds can also be done with a helix, looks more like thds, but makes a bigger file and takes more memory.

For a cosmetic thread, select the edge instead of the face, and then insert-->annotations-->cometic thread.

Automationbabe has a very good point. This one is common problem for poeple first using cosmetic threads.

In general, you have to read the docunemtation VERY carefully. It has been a couple of years, but as I recall in this case the word "edge" is used, but it not really brought out clearly that you really MUST select the edge reather than the feature.

Similar confusion used to happen between insert design table and insert design table new. One has an extra row (for the file name). If you read the doc and compare, you find that rows 1&2 become rows 2&3 depending on which type of design table you are dealing with. Never the twain shall mix. This can be extremely confusing and difficult to debug specially if you innocently do a save as from a "new design table" and try to inset it in another part to copy the same cells. It flat does not work until you delete the first row.

So, like I said - read carefully!!!!

S'me again ;-(

BTW: On the other front. Truely modelling realistic thread is something you want to avoid unless absolutely necessary for some overpowering reason. Any geometry constructed from a helix is SLOOOOOOW...... Follow the other suggestions (and read up on past threads ie: news group threads! Man this is getting complicated...). Just used the profile and revolve - works great for 99.999% of the time.

I'd like to point back to Scott's website. He is hosting a few PowerPoint Slideshows that I created on this very subject (and others). If you have Power Point, they are worth a look. They'll play in your browser window, and you only have to click your screen for the next slide.

All the way at the bottom of the page... thank you for allowing me my shameless plug.
