Yes and no.

You can edit and change multiple holes simultaneously, but not have them change automatically when you change the dimension of another object. Having said that, it might be possible if you could get constraints to work (Shark FX only), but since constraints are so badly documented and there are no tutorials your chance of success is very low.

What I do is draw the holes as circles making sure that they are all on the same plane. Then select all of the circles and use the negative extrude tool to create the holes. As all the features used to create the hoes are the same - circles, they can all be edited at the same time to the same value, similarly the distance of the cut, or depth of hole is also one feature if all the holes were made at once, so that can also be edited as a single feature.

Both of those answers are what I was looking for. Many thanks.

NickB - Never thought to use circles, just used the hole tools. I can see how starting with circles enable more control since you create the most primitive form right at the outset. When you figure out where you're going to place the hole, do you place points to mark it in 2d or 3d space?

Mikeschn - Thanks for the video but can you please kindly explain in lay mans terms how changing the dimension text caused the overall geometry to change as well? Is that utilizing something in the constraints menu? I'll admit I've never used those. It would help tremendously if you could show a brief vid tutorial of how you drew the rectangle and what constraints you used etc. Thank you!

Mikeschn, very useful. Thanks for taking the time - especially during this holiday - to make the video. With my earphones in, I could hear the audio fine. Very Merry Xmas to you as well!

Mike,
Thanks for taking the time to make the screencast.

Do you use constraints often ?
Do you think you would be up for making a few more screencast / tutorials and putting them in the Tips and Tutorials section where they could be more easily found and of more help to more people.

Misterrogers,
No I do not use points to place my circles, instead I use construction lines to initially locate them, or place them on a feature and then use the Translate (move) tool to move the circle to the location I nee. Additionally I usually place them a few mm away from the surface I want to cut to make them easier to select. If I have several holes of different sizes I will color code the circles, and sometimes place them on different planes to make them easier to select.

Something that shows how to use variables so that one dimension can govern another, so as to be able to create 4 equally spaced items, but with variable spacing so that changing one variable would change everything else.

Sorry to rant about this but . . . .
My frustration is that there is so little documentation on how to use constraints in Shark, and no tutorials available either within the program, or in this forum, yet they were supposed to be the big new enhancement / feature of V5 a few years back. A set of features or enhancements that were then quickly forgotten about by the development team.

Mike,
That is wonderful. Thank you very much.

Can I, or would you, post the link to the demo in the Tips and Tutorials section.

Nick

Mikeschn, is it possible to demonstrate how to constrain in 3D? I think I get how constraints work in a flat, 2D sketch according to your videos, but how difficult is it to constrain say a table with stretchers or a shelf all together?

If for example, the table is extended by a certain distance, how could the stretcher or shelf increase in width simultaneously? Or if the leg-height is reduced or increased, how to get all the other parts to move respectively?

Hope my query makes some sense to you.

Thank you.

Understood. Will 3D constraints be a part of future Shark versions?
